Hi,
I have a particular target (using swig / jni) that must not have -O3
-NDEBUG flags from Relase build type
How can I overload this target flags ?
Since CMAKE_<lang>_FLAGS_RELEASE does not map to a user-visible target
property, you cannot override it directly (anything added to the
COMPILE_FLAGS property is appended to the command line and does not
replace any of the compiler flags CMake sets by itself). However, you
can redefine this variable before you create your special target(s), and
then restore it so that other targets are not affected:
set(_CMAKE_CXX_FLAGS_RELEASE_SAVE ${CMAKE_CXX_FLAGS_RELEASE})
set(CMAKE_CXX_FLAGS_RELEASE)
< add your target(s) here >
set(CMAKE_CXX_FLAGS_RELEASE ${_CMAKE_CXX_FLAGS_RELEASE_SAVE})
This assumes your target is C++; if it is C, simply replace the _CXX_
with _C_.
