But that is not all the patch does.

If you do cmake -f client.txt, then every add_subdirectory and subdirs 
will now look for client.txt.   That is not the way make -f works.  If 
you do make -f it just changes the initial makefile that is read into 
make, after that it is up to the makefile writer to use include, or 
recursive make to specify additional makefiles that are included.  And, 
cmake -f client.txt would not be the same thing as make -f client.mk, as 
make -f client.mk would actually do a build.  For the cmake, one you 
would have cmake -f client.txt, make (with no -f).  I am still not 
convinced this is a good idea.
