[Cmake] MSDev multiple build types

[Dekeyser, Kris]

OK, thanks. I got that working.

One thing is disturbing me, however. The debug/optimized option is AFAIK
only available for defining link libraries. 

Why is it not available to INCLUDE_DIRECTORIES, LINK_DIRECTORIES,
ADD_(CUSTOM_COMMAND/DEFINITIONS/EXECUTABLE/LIBRARY/...),
INSTALL_(TARGETS/FILES/PROGRAMS) etc.? We can do some hacking with
CONFIGURE_FILE, but not everything is possible and adding the option support
to most of these commands would at least simplify things.
