Find-Package Tool Mode
======================
CMake provides a helper for Makefile-based projects with the signature::
cmake --find-package <options>...
This runs in a pkg-config like mode.
Search a package using :command:`find_package()` and print the resulting flags
to stdout. This can be used to use cmake instead of pkg-config to find
installed libraries in plain Makefile-based projects or in autoconf-based
projects (via ``share/aclocal/cmake.m4``).
.. note::
This mode is not well-supported due to some technical limitations.
It is kept for compatibility but should not be used in new projects.
