CMAKE_FIND_USE_CMAKE_SYSTEM_PATH

.. versionadded:: 3.16

Controls the default behavior of the following commands for whether or not to search paths provided by platform-specific cmake variables:

:command:find_program
:command:find_library
:command:find_file
:command:find_path
:command:find_package

This is useful in cross-compiling environments.

By default this variable is not set, which is equivalent to it having a value of TRUE. Explicit options given to the above commands take precedence over this variable.

See also the :variable:CMAKE_FIND_USE_CMAKE_PATH, :variable:CMAKE_FIND_USE_CMAKE_ENVIRONMENT_PATH, :variable:CMAKE_FIND_USE_INSTALL_PREFIX, :variable:CMAKE_FIND_USE_SYSTEM_ENVIRONMENT_PATH, :variable:CMAKE_FIND_USE_SYSTEM_PACKAGE_REGISTRY, :variable:CMAKE_FIND_USE_PACKAGE_REGISTRY, and :variable:CMAKE_FIND_USE_PACKAGE_ROOT_PATH variables.
