CMAKE_IGNORE_PREFIX_PATHΒΆ

New in version 3.23.

Semicolon-separated list of prefixes to be ignored by the find_program(), find_library(), find_file(), find_path(), and find_package() commands. This is useful in cross-compiling environments where some system directories contain incompatible but possibly linkable libraries. For example, on cross-compiled cluster environments, this allows a user to ignore directories containing libraries meant for the front-end machine.

By default this is empty; it is intended to be set by the project and/or the end user. Note that CMAKE_IGNORE_PREFIX_PATH takes a list of prefixes, not a list of directory names.

See also the CMAKE_PREFIX_PATH, CMAKE_LIBRARY_PATH, CMAKE_INCLUDE_PATH, and CMAKE_PROGRAM_PATH variables.
