# 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/Fortan/ASM
# MODE = EXIST : only check for existance 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
