[Cmake] MSDev multiple build types

[Dekeyser, Kris]

FYI, some feedback. Maybe something worth mentioning in the FAQ list.

I did as you suggested:

- created three template dirs 'Debug', 'Release' and 'DebugRelease'
  (DebugRelease is our internal name for RelWithDebInfo)
- copied the dsp templates to the directories along with
'CMakeVisualStudio6Configurations.cmake' and modified the files
- created a cache value BUILD_TYPE and a macro that changes the
MSPROJECT_TEMPLATE_DIRECTORY and CMAKE_BUILD_TYPE accordingly

That works like a charm. I attached a zip file with the modified templates.

Now in my CMakeLists.txt files I can detect debug configuration and set
special defines and add extra include directories and files depending on the
build type.

If anybody would like to try and do the same, beware however in how you
change the dsp templates. I don't know the specs of the DSPs and what VS6
accepts as minimal contents, but I have gathered my experiences by
trial-and-error. I was able to remove the '!IF  "$(CFG)" ==' lines and
everything in between that is not relevant to the selected build type, but I
had to be careful about removing the other stuff. You SHOULD remove all
unused targets (e.g. # Name "OUTPUT_LIBNAME - Win32 Release"), change the
CFG= line to the selected build type, but be careful about the !MESSAGE
lines beneath. On several occasions I had either VS6 refusing to load the
project or even crashing right after loading the DSPs. I changed the list of
"Possible choices for configuration" to include only the one that is
relevant, but removing the list altogether made the DSP invalid.

Generally speaking you should change the !MESSAGE lines as little as
possible and changing any lines from the last '!MESSAGE' line to the first
'!IF  "$(CFG)" ==' should be avoided completely.
