As discussed between Matthias, Albrecht and Manolo, the best procedure is - use MAC_OS_X_VERSION_MAX_ALLOWED but not __MAC_OS_X_VERSION_MAX_ALLOWED; - compile helper file CMake /macOSMaxAllowed.c to detect whether the SDK in use is in version above a given threshold version number; - based upon the result of this check, decide to weakly link or not a given framework.
