CMAKE_FIND_USE_INSTALL_PREFIX
-----------------------------------

.. versionadded:: 3.24

Controls the default behavior of the following commands for whether or not to
search the locations in the :variable:`CMAKE_INSTALL_PREFIX` and
:variable:`CMAKE_STAGING_PREFIX` variables.

* :command:`find_program`
* :command:`find_library`
* :command:`find_file`
* :command:`find_path`
* :command:`find_package`

This is useful in cross-compiling environments.

Due to backwards compatibility with :variable:`CMAKE_FIND_NO_INSTALL_PREFIX`,
the behavior of the find command change based on if this variable exists.
