CMakeFindPackageMode
--------------------
This file is executed by cmake when invoked with --find-package. It
expects that the following variables are set using -D:
``NAME``
name of the package
``COMPILER_ID``
the CMake compiler ID for which the result is,
i.e. GNU/Intel/Clang/MSVC, etc.
``LANGUAGE``
language for which the result will be used,
i.e. C/CXX/Fortran/ASM
``MODE``
``EXIST``
only check for existence of the given package
``COMPILE``
print the flags needed for compiling an object file which uses
the given package
``LINK``
print the flags needed for linking when using the given package
``QUIET``
if TRUE, don't print anything
