| CMAKE_IGNORE_PREFIX_PATH |
| ------------------------ |
| |
| :ref:`Semicolon-separated list <CMake Language Lists>` of prefix to be *ignored* by |
| the :command:`find_program`, :command:`find_library`, :command:`find_file`, |
| :command:`find_path`, and :command:`find_package` 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_PREFIX_PATH`` takes a list of prefixes, *not* |
| a list of directory names. |
| |
| See also the :variable:`CMAKE_PREFIX_PATH`, :variable:`CMAKE_LIBRARY_PATH`, |
| :variable:`CMAKE_INCLUDE_PATH`, and :variable:`CMAKE_PROGRAM_PATH` variables. |
