# CMAKE_SYSTEM_IGNORE_PATH

Semicolon-separated list 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.
