# this module defines two macros:
# MACRO_PUSH_REQUIRED_VARS()
# and
# MACRO_POP_REQUIRED_VARS()
# use these if you call cmake macros which use
# any of the CMAKE_REQUIRED_XXX variables

# Usage:
# MACRO_PUSH_REQUIRED_VARS()
# SET(CMAKE_REQUIRED_DEFINITIONS ${CMAKE_REQUIRED_DEFINITIONS} -DSOME_MORE_DEF)
# CHECK_FUNCTION_EXISTS(...)
# MACRO_POP_REQUIRED_VARS()
