[Cmake] Out of Source Builds

[William A. Hoffman]

In most cmake projects Release and Debug would not be in the subdirs of
the project.  You would do this:

aps/CMakeLists.txt
aps-debug  -- do an out of source build here cmake ../aps -D:CMAKE_BUILD_TYPE=Debug
aps-release -- do an out of source build here cmake ../aps -D:CMAKE_BUILD_TYPE=Release


For Visual Studio IDE projects the Debug and Release are handled as part
of the IDE build process.  For nmake, the above would work.
