1CMAKE_IGNORE_PATH 2----------------- 3 4:ref:`Semicolon-separated list <CMake Language Lists>` of directories to be *ignored* by 5the :command:`find_program`, :command:`find_library`, :command:`find_file`, 6and :command:`find_path` commands. This is useful in cross-compiling 7environments where some system directories contain incompatible but 8possibly linkable libraries. For example, on cross-compiled cluster 9environments, this allows a user to ignore directories containing 10libraries meant for the front-end machine. 11 12By default this is empty; it is intended to be set by the project. 13Note that ``CMAKE_IGNORE_PATH`` takes a list of directory names, *not* 14a list of prefixes. To ignore paths under prefixes (``bin``, ``include``, 15``lib``, etc.), specify them explicitly. 16 17See also the :variable:`CMAKE_PREFIX_PATH`, :variable:`CMAKE_LIBRARY_PATH`, 18:variable:`CMAKE_INCLUDE_PATH`, and :variable:`CMAKE_PROGRAM_PATH` variables. 19
