I remember trying something similar a long time ago and being equally dumbfounded. There are other inconsistencies in how CMake behaves. Changing the CMAKE_CXX_FLAGS in-between add_executable() calls also doesn't seem to work for me, for example. In the meantime you're probably can make do with set_target_properties(), specifically the COMPILE_FLAGS property. http://www.cmake.org/cmake/help/cmake2.6docs.html#command:set_target_properties -- Philip Lowman
