1) i reset it with
set( CMAKE_CXX_FLAGS ${CMAKE_CXX_FLAGS_INIT} )
set( CMAKE_CXX_FLAGS_RELEASE ${CMAKE_CXX_FLAGS_RELEASE_INIT} )
set( CMAKE_CXX_FLAGS_DEBUG ${CMAKE_CXX_FLAGS_DEBUG_INIT} )
and then append my own custom compiler definitions. "-DNDEBUG" appears in
flags.make, only in CXX_FLAGS, but not in CXX_DEFINES!
and this is the issue i had with it: as long it appears only in CXX_FLAGS, it
works for the code compilation but it does not work for qt4_wrapp_cpp (missing
defines for moc).
2) the point i want to change global compiler properties is in my toplevel
CMakeLists.txt,
there i do
include( cmake/GlobalCompilerSettings.cmake)
3) following your example, it does not work for COMPILE_DEFINITIONS_RELEASE,
but does work for COMPILE_DEFINITIONS.
(works means it appears in CXX_DEFINES)
using release cmake 3.0.0 version. Platform is ubuntu linux (makefile generator)
