[Cmake] subdirs please change it.

[Andy Cedilnik]

Hi Klaas,

I agree with you all the way, but unfortunately the current design of
CMake does not allow that.

I can suggest you this option:

1. Use INCLUDE instead of SUBDIRS. INCLUDE happens when it is
encountered, so you have full control over it. Also, there will not be
recursive Makefile problem since all your code will be compiled by the
toplevel Makefile. The drawbacks are that you will have to specify full
path to sources and CMAKE_CURRENT_(BINARY/SOURCE)_DIR will not work.
