CMAKE_IGNORE_PATH ----------------- :ref:`Semicolon-separated list ` of directories to be *ignored* by the :command:`find_program`, :command:`find_library`, :command:`find_file`, and :command:`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 :variable:`CMAKE_PREFIX_PATH`, :variable:`CMAKE_LIBRARY_PATH`, :variable:`CMAKE_INCLUDE_PATH`, and :variable:`CMAKE_PROGRAM_PATH` variables.
