[CMake] Working with Multiple Projects

[Petr Kmoch]

As far as I know, you can't have two CMake projects in the same
directory. Move one of the CMakeLists.txt files to a different one -
either create a sudirectory for the subproject, or create a separate
directory for the "top-level" CMakeLists.txt.

Note that there is no need for directories added via ADD_SUBDIRECTORY
to be actually subdirectories of the source dir. I.e.
ADD_SUBDIRECTORY("../../SomeDir") is perfectly valid.
