FindASPELL — CMake 4.2.6 Documentation

# FindASPELL

Finds the GNU Aspell spell checker library:

    find_package(ASPELL [<version>] [COMPONENTS <components>] [...])

## Components

This module supports optional components which can be specified using the `find_package()` command:

    find_package(ASPELL [COMPONENTS <components>...])

Supported components include:

`ASPELL`

  Added in version 4.1.

  Finds the Aspell library and its include paths.

`Executable`

  Added in version 4.1.

  Finds the Aspell command-line interactive spell checker executable.

If no components are specified, the module searches for both the `ASPELL` and `Executable` components by default.

## Imported Targets

This module provides the following Imported Targets when `CMAKE_ROLE` is `PROJECT`:

`ASPELL::ASPELL`

  Added in version 4.1.

  Target encapsulating the Aspell library usage requirements. It is available only when the `ASPELL` component is found.

`ASPELL::Executable`

  Added in version 4.1.

  Target encapsulating the Aspell command-line spell checker executable. It is available only when the `Executable` component is found.

## Result Variables

This module defines the following variables:

`ASPELL_FOUND`

  Boolean indicating whether (the requested version of) Aspell and all requested components were found.

`ASPELL_VERSION`

  Added in version 4.1.

  Version string of the found Aspell if any. It may be only determined if the `Executable` component is found. If version isn't determined, version value is not set.

`ASPELL_INCLUDE_DIRS`

  Added in version 4.1.

  Include directories needed to use Aspell. They are available when the `ASPELL` component is found.

  The Aspell library may also provide a backward-compatible interface for Pspell via the `pspell.h` header file. If such an interface is found, it is also added to the list of include directories.

`ASPELL_LIBRARIES`

  Libraries needed to link to Aspell. They are available when the `ASPELL` component is found.

  Changed in version 4.1: This variable is now set as a regular result variable instead of being a cache variable.

## Cache Variables

The following cache variables may also be set:

`ASPELL_INCLUDE_DIR`

  The directory containing the `aspell.h` header file when using the `Executable` component.

`ASPELL_LIBRARY`

  Added in version 4.1.

  The path to the Aspell library when using the `ASPELL` component.

`ASPELL_EXECUTABLE`

  The path to the `aspell` command-line spell checker program when using the `Executable` component.

## Examples

Finding the Aspell library with CMake 4.1 or later and linking it to a project target:

    find_package(ASPELL COMPONENTS ASPELL)
    target_link_libraries(project_target PRIVATE ASPELL::ASPELL)

When writing backward-compatible code that supports CMake 4.0 and earlier, a local imported target can be defined directly in the project:

    find_package(ASPELL COMPONENTS ASPELL)
    if(ASPELL_FOUND AND NOT TARGET ASPELL::ASPELL)
      add_library(ASPELL::ASPELL INTERFACE IMPORTED)
      set_target_properties(
        ASPELL::ASPELL
        PROPERTIES
          INTERFACE_LINK_LIBRARIES "${ASPELL_LIBRARIES}"
          INTERFACE_INCLUDE_DIRECTORIES "${ASPELL_INCLUDE_DIR}"
      )
    endif()
    target_link_libraries(project_target PRIVATE ASPELL::ASPELL)

Example, how to execute the `aspell` command-line spell checker in a project:

    find_package(ASPELL COMPONENTS Executable)
    execute_process(COMMAND ${ASPELL_EXECUTABLE} --help)
