Hi,
Is there a way to specify different warning levels for debug and release?
Under Visual Studio 2003 we like to build debug with warning level 4,
and release at warning level 3.
Can CMake do this?
I don't know if Visual Studio uses CFLAGS for warning level (I assume it
does), but this is how I'd do it for gcc:
IF(CMAKE_COMPILER_IS_GNUCC)
SET(CMAKE_C_FLAGS_DEBUG -g -Wall -Werror)
SET(CMAKE_C_FLAGS_RELEASE -O2 -pipe -fomit-frame-pointer -DNDEBUG)
# And the other build types if necessary
ENDIF(CMAKE_COMPILER_IS_GNUCC)
Similarly, you can test for CMAKE_COMPILER_IS_GNUCXX and set
CMAKE_CXX_FLAGS_*
The CFLAG variable used depends on CMAKE_BUILD_TYPE: None, Debug,
Release, RelWithDebInfo, MinSizeRel, each of which corresponding to an
appropriate CMAKE_LANG_FLAGS_TYPE entry in the cache.
Perhaps testing on IF(MSVC) will be helpful for you. See
