[CMake] How to specify default build dir in CMakeLists.txt?

[Kedzierski, Artur CIV NAVSURFWARCENDIV CORONA]

	It would be something like:
${CMAKE_SOURCE_DIR)/build
	In other words it would be a subdirectory of the top-level
source dir. 
	Yes, it would be annoying if the default was set to 'c:\'
or '/tmp/'.  However, it is safe to assume that if the user can
compile source in '/some/dir/ (in-source)', he should also be able 
to compile in '/some/dir/build' (subdir of source but out-of-source).
	Again, this is just a default so the user wouldn't be forced to
use that directory.

That means you'd have to pick an out-of-source directory for the user.  
What do you imagine would be a non-annoying choice?  Do you have enough 
knowledge of the user's system to know where he wants to build stuff?  I 
think not.

I think what you really want are platform-specific subdirectories for 
building in your own source tree.
