;-list <CMake Language Lists> of directories to be ignored by the find_program, find_library, find_file, and find_path 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 contains a list of directories containing incompatible binaries for the host system. See the CMAKE_IGNORE_PATH variable that is intended to be set by the project.
See also the CMAKE_SYSTEM_PREFIX_PATH, CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_SYSTEM_INCLUDE_PATH, and CMAKE_SYSTEM_PROGRAM_PATH variables.
