Actually, if someone on OS X decides to generate Makefiles then
CMAKE_BUILD_TYPE can be very important.
You can simply do what you are doing and it _should_ work. The order
of operations in a CMake file, like any other language, is important.
It just depends on what is after those lines that you insert will
determine what gets used and what does not.

How do you tell Cmake to add a compiler flag to a project's Debug
target?
In a project I'm trying to fix (OpenSceneGraph) it looks like Cmake
generates an Xcode project file containing all four of the build
types:
Debug, Release, ReleaseMinSize, and RelWithDebInfo. These types can be
selected from within Xcode. Is it therefore true that there is no need
to set CMAKE_BUILD_TYPE on OSX? To gain understanding of what cmake is
doing, I have the following lines at the beginning of the
CMakeLists.txt:
SET(COMPILE_DEFINITIONS_DEBUG ${COMPILE_DEFINITIONS_DEBUG} -D_DEBUG=2)
SET(CMAKE_CXX_FLAGS_DEBUG ${CMAKE_CXX_FLAGS_DEBUG} -D_DEBUG=3)
SET(CMAKE_C_FLAGS_DEBUG ${CMAKE_C_FLAGS_DEBUG} -D_DEBUG=4)
add_definitions(-D_DEBUG=5)
And I put these lines at the end of the file:
SET(COMPILE_DEFINITIONS_DEBUG ${COMPILE_DEFINITIONS_DEBUG} -D_DEBUG=6)
SET(CMAKE_CXX_FLAGS_DEBUG ${CMAKE_CXX_FLAGS_DEBUG} -D_DEBUG=7)
SET(CMAKE_C_FLAGS_DEBUG ${CMAKE_C_FLAGS_DEBUG} -D_DEBUG=8)
add_definitions(-D_DEBUG=9)
When I look in the build directory I only see instances of "-
D_DEBUG=5"
and "-D_DEBUG=9". The Cmake documentation implies that at least one of
the other lines should do *something*, but they appear to do nothing.
Can anyone explain what is going on? Thanks.
