# CMAKE_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 is empty; it is intended to be set by the project. Note that `CMAKE_IGNORE_PATH` takes a list of directory names, not a list of prefixes. To ignore paths under prefixes (`bin`, `include`, `lib`, etc.), specify them explicitly.

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