How can I use cmake to do the same thing?
Add your -g flag to CMAKE_CXX_FLAGS or I think you can use
ADD_DEFINITIONS("-g").
It would be better to edit the CMAKE_CXX_FLAGS_DEBUG cache variable.
add_definitions(-g) is bad for a several reasons...
It will break for compilers that do not accept -g, it will add -g to
release and optimized builds.
If the compiler doesn't support -g, how would using CMAKE_CXX_FLAGS_*
help?
If one wanted -g in all configurations, is ADD_DEFINITIONS then an
acceptable solution, or is there other badness there?
Generally, add_definitions was intended for -D stuff, and not compiler
flags. Compiler flags were meant to go into the cache variables.
