cmake_minimum_required(VERSION 3.7)

# at least cmake 3.7 is required for:
# * to request source directory path from target:
#   `get_target_property(FOO_SOURCE_DIR Foo SOURCE_DIR)`
# * to request BUILDSYSTEM_TARGETS property from a directory.
#

# at least cmake 3.3 is required for:
# * to use IN_LIST in if command:
#   (https://cmake.org/cmake/help/v3.3/command/if.html )
#   `if(<variable|string> IN_LIST <variable>)`
