# CPack RPM Generator

The built in (binary) CPack RPM generator (Unix only)

## Variables specific to CPack RPM generator

The CPack RPM generator may be used to create RPM packages using `CPack`. The CPack RPM generator is a `CPack` generator thus it uses the `CPACK_XXX` variables used by `CPack`.

The CPack RPM generator has specific features which are controlled by the specifics `CPACK_RPM_XXX` variables.

`CPACK_RPM_<COMPONENT>_XXXX` variables may be used in order to have component-specific values. Note however that `<COMPONENT>` refers to the grouping name written in upper case. It may be either a component name or a component GROUP name. Usually, those variables correspond to RPM spec file entities. One may find information about spec files here https://rpm.org/documentation.

Changed in version 3.6: `<COMPONENT>` part of variables is preferred to be in upper case (e.g. if component is named `foo` then use `CPACK_RPM_FOO_XXXX` variable name format) as is with other `CPACK_<COMPONENT>_XXXX` variables. For the purposes of back compatibility (CMake/CPack version 3.5 and lower) support for same cased component (e.g. `fOo` would be used as `CPACK_RPM_fOo_XXXX`) is still supported for variables defined in older versions of CMake/CPack but is not guaranteed for variables that will be added in the future. For the sake of back compatibility same cased component variables also override upper cased versions where both are present.

Here are some CPack RPM generator wiki resources that are here for historic reasons and are no longer maintained but may still prove useful:

List of CPack RPM generator specific variables:

CPACK_RPM_COMPONENT_INSTALL

  Enable component packaging for CPack RPM generator

  Mandatory:

    No

  Default:

    `OFF`

  If enabled (`ON`) multiple packages are generated. By default a single package containing files of all components is generated.

CPACK_RPM_PACKAGE_SUMMARY
CPACK_RPM_<component>_PACKAGE_SUMMARY

  The RPM package summary.

  Mandatory:

    Yes

  Default:

    `CPACK_PACKAGE_DESCRIPTION_SUMMARY`

  Added in version 3.2: Per-component `CPACK_RPM_<component>_PACKAGE_SUMMARY` variables.

CPACK_RPM_PACKAGE_NAME
CPACK_RPM_<component>_PACKAGE_NAME

  The RPM package name.

  Mandatory:

    Yes

  Default:

    `CPACK_PACKAGE_NAME`

  Added in version 3.5: Per-component `CPACK_RPM_<component>_PACKAGE_NAME` variables.

CPACK_RPM_FILE_NAME
CPACK_RPM_<component>_FILE_NAME

  Added in version 3.6.

  Package file name.

  Mandatory:

    Yes

  Default:

    `<CPACK_PACKAGE_FILE_NAME>[-<component>].rpm` with spaces replaced by '-'

  This may be set to:

  `RPM-DEFAULT`

    Tell `rpmbuild` to automatically generate the package file name.

  `<file-name>[.rpm]`

    Use the given file name.

    Changed in version 3.29: The `.rpm` suffix will be automatically added if missing. Previously the suffix was required.

  Note

  By using user provided spec file, rpm macro extensions such as for generating `debuginfo` packages or by simply using multiple components more than one rpm file may be generated, either from a single spec file or from multiple spec files (each component execution produces its own spec file). In such cases duplicate file names may occur as a result of this variable setting or spec file content structure. Duplicate files get overwritten and it is up to the packager to set the variables in a manner that will prevent such errors.

CPACK_RPM_MAIN_COMPONENT

  Added in version 3.8.

  Main component that is packaged without component suffix.

  Mandatory:

    No

  Default:

  This variable can be set to any component or group name so that component or group rpm package is generated without component suffix in filename and package name.

CPACK_RPM_PACKAGE_EPOCH

  Added in version 3.10.

  The RPM package epoch

  Mandatory:

    No

  Default:

  Optional number that should be incremented when changing versioning schemas or fixing mistakes in the version numbers of older packages.

CPACK_RPM_PACKAGE_RELEASE

  The RPM package release.

  Mandatory:

    Yes

  Default:

    1

  This is the numbering of the RPM package itself, i.e. the version of the packaging and not the version of the content (see `CPACK_RPM_PACKAGE_VERSION`). One may change the default value if the previous packaging was buggy and/or you want to put here a fancy Linux distro specific numbering.

Note

This is the string that goes into the RPM `Release:` field. Some distros (e.g. Fedora, CentOS) require `1%{?dist}` format and not just a number. `%{?dist}` part can be added by setting `CPACK_RPM_PACKAGE_RELEASE_DIST`.

CPACK_RPM_PACKAGE_RELEASE_DIST

  Added in version 3.6.

CPACK_RPM_PACKAGE_RELOCATABLE

  build a relocatable RPM.

  Mandatory:

    No

  Default:

    CPACK_PACKAGE_RELOCATABLE

  If this variable is set to TRUE or ON, the CPack RPM generator will try to build a relocatable RPM package. A relocatable RPM may be installed using:

      rpm --prefix or --relocate

  in order to install it at an alternate place see rpm(8). Note that currently this may fail if `CPACK_SET_DESTDIR` is set to `ON`. If `CPACK_SET_DESTDIR` is set then you will get a warning message but if there is file installed with absolute path you'll get unexpected behavior.

CPACK_RPM_SPEC_INSTALL_POST

  Deprecated since version 2.8.12: Use `CPACK_RPM_SPEC_MORE_DEFINE` instead.

  Mandatory:

    No

  Default:

  May be used to override the `__spec_install_post` section within the generated spec file. This affects the install step during package creation, not during package installation. For adding operations to be performed during package installation, use `CPACK_RPM_POST_INSTALL_SCRIPT_FILE` instead.

CPACK_RPM_SPEC_MORE_DEFINE

  RPM extended spec definitions lines.

  Mandatory:

    No

  Default:

  May be used to add any `%define` lines to the generated spec file. An example of its use is to prevent stripping of executables (but note that this may also disable other default post install processing):

      set(CPACK_RPM_SPEC_MORE_DEFINE "%define __spec_install_post /bin/true")

  Added in version 4.4: If the variable is a list, its string elements will be concatenated using `\n` before being substituted into the spec template.

CPACK_RPM_PACKAGE_DEBUG

  Toggle CPack RPM generator debug output.

  Mandatory:

    No

  Default:

  May be set when invoking cpack in order to trace debug information during CPack RPM run. For example you may launch CPack like this:

      cpack -D CPACK_RPM_PACKAGE_DEBUG=1 -G RPM

CPACK_RPM_USER_BINARY_SPECFILE
CPACK_RPM_<componentName>_USER_BINARY_SPECFILE

  A user provided spec file.

  Mandatory:

    No

  Default:

  May be set by the user in order to specify a USER binary spec file to be used by the CPack RPM generator instead of generating the file. The specified file will be processed by configure_file(@ONLY).

CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE

  Spec file template.

  Mandatory:

    No

  Default:

  If set CPack will generate a template for USER specified binary spec file and stop with an error. For example launch CPack like this:

      cpack -D CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE=1 -G RPM

  The user may then use this file in order to hand-craft is own binary spec file which may be used with `CPACK_RPM_USER_BINARY_SPECFILE`.

CPACK_RPM_PRE_INSTALL_SCRIPT_FILE
CPACK_RPM_PRE_UNINSTALL_SCRIPT_FILE
CPACK_RPM_PRE_TRANS_SCRIPT_FILE

  Path to file containing pre install/uninstall/transaction script.

  Mandatory:

    No

  Default:

  May be used to embed a pre installation/uninstallation/transaction script in the spec file. The referred script file (or both) will be read and directly put after the `%pre` or `%preun` section If `CPACK_RPM_COMPONENT_INSTALL` is set to ON the install/uninstall/transaction script for each component can be overridden with `CPACK_RPM_<COMPONENT>_PRE_INSTALL_SCRIPT_FILE`, `CPACK_RPM_<COMPONENT>_PRE_UNINSTALL_SCRIPT_FILE`, and `CPACK_RPM_<COMPONENT>_PRE_TRANS_SCRIPT_FILE` One may verify which scriptlet has been included with:

      rpm -qp --scripts  package.rpm

  Added in version 3.18: The `CPACK_RPM_PRE_TRANS_SCRIPT_FILE` variable.

CPACK_RPM_POST_INSTALL_SCRIPT_FILE
CPACK_RPM_POST_UNINSTALL_SCRIPT_FILE
CPACK_RPM_POST_TRANS_SCRIPT_FILE

  Path to file containing post install/uninstall/transaction script.

  Mandatory:

    No

  Default:

  May be used to embed a post installation/uninstallation/transaction script in the spec file. The referred script file (or both) will be read and directly put after the `%post` or `%postun` section. If `CPACK_RPM_COMPONENT_INSTALL` is set to ON the install/uninstall/transaction script for each component can be overridden with `CPACK_RPM_<COMPONENT>_POST_INSTALL_SCRIPT_FILE`, `CPACK_RPM_<COMPONENT>_POST_UNINSTALL_SCRIPT_FILE`, and `CPACK_RPM_<COMPONENT>_POST_TRANS_SCRIPT_FILE` One may verify which scriptlet has been included with:

      rpm -qp --scripts  package.rpm

  Added in version 3.18: The `CPACK_RPM_POST_TRANS_SCRIPT_FILE` variable.

CPACK_RPM_USER_FILELIST
CPACK_RPM_<COMPONENT>_USER_FILELIST
  Mandatory:

    No

  Default:

  May be used to explicitly specify `%(<directive>)` file line in the spec file. Like `%config(noreplace)` or any other directive that be found in the `%files` section. Since the CPack RPM generator is generating the list of files (and directories) the user specified files of the `CPACK_RPM_<COMPONENT>_USER_FILELIST` list will be removed from the generated list. If referring to directories do not add a trailing slash.

  Added in version 3.8: You can have multiple directives per line, as in `%attr(600,root,root) %config(noreplace)`.

CPACK_RPM_CHANGELOG_FILE

  RPM changelog file.

  Mandatory:

    No

  Default:

  May be used to embed a changelog in the spec file. The referred file will be read and directly put after the `%changelog` section.

CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST

  list of path to be excluded.

  Mandatory:

    No

  Default:
    The following paths are excluded by default:

      - `/etc`

      - `/etc/init.d`

      - `/usr`

      - `/usr/bin`

      - `/usr/include`

      - `/usr/lib`

      - `/usr/libx32`

      - `/usr/lib64`

      - `/usr/share`

      - `/usr/share/aclocal`

      - `/usr/share/doc`

  May be used to exclude path (directories or files) from the auto-generated list of paths discovered by CPack RPM. The default value contains a reasonable set of values if the variable is not defined by the user. If the variable is defined by the user then the CPack RPM generator will NOT any of the default path. If you want to add some path to the default list then you can use `CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION` variable.

  Added in version 3.10: Added `/usr/share/aclocal` to the default list of excludes.

CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION

  additional list of path to be excluded.

  Mandatory:

    No

  Default:

  May be used to add more exclude path (directories or files) from the initial default list of excluded paths. See `CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST`.

CPACK_RPM_RELOCATION_PATHS

  Added in version 3.2.

  Packages relocation paths list.

  Mandatory:

    No

  Default:

  May be used to specify more than one relocation path per relocatable RPM. Variable contains a list of relocation paths that if relative are prefixed by the value of `CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX` or by the value of `CPACK_PACKAGING_INSTALL_PREFIX` if the component version is not provided. Variable is not component based as its content can be used to set a different path prefix for e.g. binary dir and documentation dir at the same time. Only prefixes that are required by a certain component are added to that component - component must contain at least one file/directory/symbolic link with `CPACK_RPM_RELOCATION_PATHS` prefix for a certain relocation path to be added. Package will not contain any relocation paths if there are no files/directories/symbolic links on any of the provided prefix locations. Packages that either do not contain any relocation paths or contain files/directories/symbolic links that are outside relocation paths print out an `AUTHOR_WARNING` that RPM will be partially relocatable.

CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX

  Added in version 3.2.

  Per component relocation path install prefix.

  Mandatory:

    No

  Default:

    `CPACK_PACKAGING_INSTALL_PREFIX`

  May be used to set per component `CPACK_PACKAGING_INSTALL_PREFIX` for relocatable RPM packages.

CPACK_RPM_NO_INSTALL_PREFIX_RELOCATION
CPACK_RPM_NO_<COMPONENT>_INSTALL_PREFIX_RELOCATION

  Added in version 3.3.

  Removal of default install prefix from relocation paths list.

  Mandatory:

    No

  Default:

    `CPACK_PACKAGING_INSTALL_PREFIX` or `CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX` are treated as one of relocation paths

  May be used to remove `CPACK_PACKAGING_INSTALL_PREFIX` and `CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX` from relocatable RPM prefix paths.

CPACK_RPM_ADDITIONAL_MAN_DIRS

  Added in version 3.3.

  Mandatory:

    No

  Default:
    Regular expressions that are added by default were taken from `brp-compress` RPM macro:

      - `/usr/man/man.*`

      - `/usr/man/.*/man.*`

      - `/usr/info.*`

      - `/usr/share/man/man.*`

      - `/usr/share/man/.*/man.*`

      - `/usr/share/info.*`

      - `/usr/kerberos/man.*`

      - `/usr/X11R6/man/man.*`

      - `/usr/lib/perl5/man/man.*`

      - `/usr/share/doc/.*/man/man.*`

      - `/usr/lib/.*/man/man.*`

  May be used to set additional man dirs that could potentially be compressed by brp-compress RPM macro. Variable content must be a list of regular expressions that point to directories containing man files or to man files directly. Note that in order to compress man pages a path must also be present in brp-compress RPM script and that brp-compress script must be added to RPM configuration by the operating system.

CPACK_RPM_DEFAULT_USER
CPACK_RPM_<compName>_DEFAULT_USER

  Added in version 3.6.

  default user ownership of RPM content

  Mandatory:

    No

  Default:

    `root`

  Value should be user name and not UID. Note that `<compName>` must be in upper-case.

CPACK_RPM_DEFAULT_GROUP
CPACK_RPM_<compName>_DEFAULT_GROUP

  Added in version 3.6.

  default group ownership of RPM content

  Mandatory:

    No

  Default:

    root

  Value should be group name and not GID. Note that `<compName>` must be in upper-case.

CPACK_RPM_DEFAULT_FILE_PERMISSIONS
CPACK_RPM_<compName>_DEFAULT_FILE_PERMISSIONS

  Added in version 3.6.

  default permissions used for packaged files

  Mandatory:

    No

  Default:

    (system default)

  Accepted values are lists with PERMISSIONS. Valid permissions are:

  - `OWNER_READ`

  - `OWNER_WRITE`

  - `OWNER_EXECUTE`

  - `GROUP_READ`

  - `GROUP_WRITE`

  - `GROUP_EXECUTE`

  - `WORLD_READ`

  - `WORLD_WRITE`

  - `WORLD_EXECUTE`

  Note that `<compName>` must be in upper-case.

CPACK_RPM_DEFAULT_DIR_PERMISSIONS
CPACK_RPM_<compName>_DEFAULT_DIR_PERMISSIONS

  Added in version 3.6.

  default permissions used for packaged directories

  Mandatory:

    No

  Default:

    (system default)

  Accepted values are lists with PERMISSIONS. Valid permissions are the same as for `CPACK_RPM_DEFAULT_FILE_PERMISSIONS`. Note that `<compName>` must be in upper-case.

CPACK_RPM_INSTALL_WITH_EXEC

  Added in version 3.11.

  force execute permissions on programs and shared libraries

  Mandatory:

    No

  Default:

    (system default)

  Force set owner, group and world execute permissions on programs and shared libraries. This can be used for creating valid rpm packages on systems such as Debian where shared libraries do not have execute permissions set.

Note

Programs and shared libraries without execute permissions are ignored during separation of debug symbols from the binary for debuginfo packages.

## Packaging of Symbolic Links

Added in version 3.3.

The CPack RPM generator supports packaging of symbolic links:

    execute_process(COMMAND ${CMAKE_COMMAND}
      -E create_symlink <relative_path_location> <symlink_name>)
    install(FILES ${CMAKE_CURRENT_BINARY_DIR}/<symlink_name>
      DESTINATION <symlink_location> COMPONENT libraries)

Symbolic links will be optimized (paths will be shortened if possible) before being added to the package or if multiple relocation paths are detected, a post install symlink relocation script will be generated.

Symbolic links may point to locations that are not packaged by the same package (either a different component or even not packaged at all) but those locations will be treated as if they were a part of the package while determining if symlink should be either created or present in a post install script - depending on relocation paths.

Changed in version 3.6: Symbolic links that point to locations outside packaging path produce a warning and are treated as non relocatable permanent symbolic links. Previous versions of CMake produced an error in this case.

Currently there are a few limitations though:

- For component based packaging component interdependency is not checked when processing symbolic links. Symbolic links pointing to content of a different component are treated the same way as if pointing to location that will not be packaged.

- Symbolic links pointing to a location through one or more intermediate symbolic links will not be handled differently - if the intermediate symbolic link(s) is also on a relocatable path, relocating it during package installation may cause initial symbolic link to point to an invalid location.

## Packaging of debug information

Added in version 3.7.

Debuginfo packages contain debug symbols and sources for debugging packaged binaries.

Debuginfo RPM packaging has its own set of variables:

CPACK_RPM_DEBUGINFO_PACKAGE
CPACK_RPM_<component>_DEBUGINFO_PACKAGE

  Enable generation of debuginfo RPM package(s).

  Mandatory:

    No

  Default:

    `OFF`

Note

Binaries must contain debug symbols before packaging so use either `Debug` or `RelWithDebInfo` for `CMAKE_BUILD_TYPE` variable value.

Additionally, if `CPACK_STRIP_FILES` is set, the files will be stripped before they get to the RPM generator, so will not contain debug symbols and a debuginfo package will not get built. Do not use with `CPACK_STRIP_FILES`.

Note

Packages generated from packages without binary files, with binary files but without execute permissions or without debug symbols will cause packaging termination.

CPACK_BUILD_SOURCE_DIRS

  Provides locations of root directories of source files from which binaries were built.

  Mandatory:

    Yes if `CPACK_RPM_DEBUGINFO_PACKAGE` is set

  Default:

Note

For CMake project `CPACK_BUILD_SOURCE_DIRS` is set by default to point to `CMAKE_SOURCE_DIR` and `CMAKE_BINARY_DIR` paths.

Note

Sources with path prefixes that do not fall under any location provided with `CPACK_BUILD_SOURCE_DIRS` will not be present in debuginfo package.

CPACK_RPM_BUILD_SOURCE_DIRS_PREFIX
CPACK_RPM_<component>_BUILD_SOURCE_DIRS_PREFIX

  Prefix of location where sources will be placed during package installation.

  Mandatory:

    Yes if `CPACK_RPM_DEBUGINFO_PACKAGE` is set

  Default:

    `/usr/src/debug/${CPACK_PACKAGE_FILE_NAME}` and for component packaging `/usr/src/debug/${CPACK_PACKAGE_FILE_NAME}-<component>`

Note

Each source path prefix is additionally suffixed by `src_<index>` where index is index of the path used from `CPACK_BUILD_SOURCE_DIRS` variable. This produces `${CPACK_RPM_BUILD_SOURCE_DIRS_PREFIX}/src_<index>` replacement path. Limitation is that replaced path part must be shorter or of equal length than the length of its replacement. If that is not the case either `CPACK_RPM_BUILD_SOURCE_DIRS_PREFIX` variable has to be set to a shorter path or source directories must be placed on a longer path.

CPACK_RPM_DEBUGINFO_EXCLUDE_DIRS

  Directories containing sources that should be excluded from debuginfo packages.

  Mandatory:

    No

  Default:
    The following paths are excluded by default:

      - `/usr`

      - `/usr/src`

      - `/usr/src/debug`

  Listed paths are owned by other RPM packages and should therefore not be deleted on debuginfo package uninstallation.

CPACK_RPM_DEBUGINFO_EXCLUDE_DIRS_ADDITION

  Paths that should be appended to `CPACK_RPM_DEBUGINFO_EXCLUDE_DIRS` for exclusion.

  Mandatory:

    No

  Default:

CPACK_RPM_DEBUGINFO_SINGLE_PACKAGE

  Added in version 3.8.

  Create a single debuginfo package even if components packaging is set.

  Mandatory:

    No

  Default:

    `OFF`

  When this variable is enabled it produces a single debuginfo package even if component packaging is enabled.

  When using this feature in combination with components packaging and there is more than one component this variable requires `CPACK_RPM_MAIN_COMPONENT` to be set.

Note

If none of the `CPACK_RPM_<component>_DEBUGINFO_PACKAGE` variables is set then `CPACK_RPM_DEBUGINFO_PACKAGE` is automatically set to `ON` when `CPACK_RPM_DEBUGINFO_SINGLE_PACKAGE` is set.

CPACK_RPM_DEBUGINFO_FILE_NAME
CPACK_RPM_<component>_DEBUGINFO_FILE_NAME

  Added in version 3.9.

  Debuginfo package file name.

  Mandatory:

    No

  Default:

    rpmbuild tool generated package file name

  Alternatively provided debuginfo package file name must end with `.rpm` suffix and should differ from file names of other generated packages.

  Variable may contain `@cpack_component@` placeholder which will be replaced by component name if component packaging is enabled otherwise it deletes the placeholder.

  Setting the variable to `RPM-DEFAULT` may be used to explicitly set filename generation to default.

Note

`CPACK_RPM_FILE_NAME` also supports rpmbuild tool generated package file name - disabled by default but can be enabled by setting the variable to `RPM-DEFAULT`.

## Packaging of sources (SRPM)

Added in version 3.7.

SRPM packaging is enabled by setting `CPACK_RPM_PACKAGE_SOURCES` variable while usually using `CPACK_INSTALLED_DIRECTORIES` variable to provide directory containing CMakeLists.txt and source files.

For CMake projects SRPM package would be produced by executing:

    cpack -G RPM --config ./CPackSourceConfig.cmake

Note

Produced SRPM package is expected to be built with `cmake(1)` executable and packaged with `cpack(1)` executable so CMakeLists.txt has to be located in root source directory and must be able to generate binary rpm packages by executing `cpack -G` command. The two executables as well as rpmbuild must also be present when generating binary rpm packages from the produced SRPM package.

Once the SRPM package is generated it can be used to generate binary packages by creating a directory structure for rpm generation and executing rpmbuild tool:

    mkdir -p build_dir/{BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS}
    rpmbuild --define "_topdir <path_to_build_dir>" --rebuild <SRPM_file_name>

Generated packages will be located in build_dir/RPMS directory or its sub directories.

Note

SRPM package internally uses CPack/RPM generator to generate binary packages so CMakeScripts.txt can decide during the SRPM to binary rpm generation step what content the package(s) should have as well as how they should be packaged (monolithic or components). CMake can decide this for e.g. by reading environment variables set by the package manager before starting the process of generating binary rpm packages. This way a single SRPM package can be used to produce different binary rpm packages on different platforms depending on the platform's packaging rules.

Source RPM packaging has its own set of variables:

CPACK_RPM_PACKAGE_SOURCES

  Should the content be packaged as a source rpm (default is binary rpm).

  Mandatory:

    No

  Default:

    `OFF`

Note

For cmake projects `CPACK_RPM_PACKAGE_SOURCES` variable is set to `OFF` in CPackConfig.cmake and `ON` in CPackSourceConfig.cmake generated files.

CPACK_RPM_SOURCE_PKG_BUILD_PARAMS

  Additional command-line parameters provided to `cmake(1)` executable.

  Mandatory:

    No

  Default:

CPACK_RPM_SOURCE_PKG_PACKAGING_INSTALL_PREFIX

  Packaging install prefix that would be provided in `CPACK_PACKAGING_INSTALL_PREFIX` variable for producing binary RPM packages.

  Mandatory:

    Yes

  Default:

    `/`

CPACK_RPM_BUILDREQUIRES

  List of source rpm build dependencies.

  Mandatory:

    No

  Default:

  May be used to set source RPM build dependencies (BuildRequires). Note that you must enclose the entire value between quotes when setting this variable, for example:

      set(CPACK_RPM_BUILDREQUIRES "python >= 2.5.0, cmake >= 2.8")

CPACK_RPM_REQUIRES_EXCLUDE_FROM

  Added in version 3.22.

  Mandatory:

    No

  Default:

  May be used to keep the dependency generator from scanning specific files or directories for dependencies. Note that you can use a regular expression that matches all of the directories or files, for example:

      set(CPACK_RPM_REQUIRES_EXCLUDE_FROM "bin/libqsqloci.*\\.so.*")
