# 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() |
