Edit File: CMakeFindPackageMode.cmake

# 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 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
