Currently the system is modelled after the Scons system, so in places
where wildcards for sources were used I used wildcards and in places
where it was not I didn't. In most places though wildcards are used,
so if a person runs cmake generation directly after doing a get the
projects and makefiles should be correct, so this has to be added to
the developer's workflow that plans to make use of this system.

I have been using a clean source tree every time, so have not run into
this, but I also do not use the make system. Is this not a problem
with the verse makefiles writing output directly into the sources
instead of the build directory? I will change the folder name for the
mkprot subdir to not interfere with the make system if people use both
for some reason.

I tried to minimize the number of options available to simplify things
for the developers, so I used autodetection cmake scripts where
available. OpenAL is supposed to be turned off automatically if not
detected. What platform are you using? I will fix this or add an
One other question; OpenAL and SDL does not seem to be mutually
exclusive in blender build, if there is an option it could just be
WITH_SOUND which will require both libraries right?

I have been using the command line interface and used the MESSAGE
command to output the configuration stage. It does however give some
progress feedback for command line usage, I will change the message
types to STATUS all over, which will give feedback in the status bar
instead in the UI.
