CMAKE_SYSTEM_IGNORE_PATH
------------------------

:ref:`;-list <CMake Language Lists>` 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 contains a list of directories containing incompatible
binaries for the host system.  See the :variable:`CMAKE_IGNORE_PATH` variable
that is intended to be set by the project.

See also the :variable:`CMAKE_SYSTEM_PREFIX_PATH`,
:variable:`CMAKE_SYSTEM_LIBRARY_PATH`, :variable:`CMAKE_SYSTEM_INCLUDE_PATH`,
and :variable:`CMAKE_SYSTEM_PROGRAM_PATH` variables.
