CMAKE_IGNORE_PREFIX_PATH
------------------------
.. versionadded:: 3.23
:ref:`Semicolon-separated list <CMake Language Lists>` of prefixes 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 and/or
the end user. 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.
