This actually isn't necessary. We've been using CMake for a number of 
years to build libraries and applications for multiple targets from the 
same source tree. Using CMake '-D' command line options allow variables 
to be set within CMake.  A CMake file can also conditionally include 
other CMake file fragments. We use this to select cross compile 
toolsets, different support libraries, (etc). We actually have a 
directory structure similar to boost where object files are held in 
compile target specific sub-trees. This all works pretty well but there 
are a few CMake syntax convenience improvements that would be nice to 
have (e.g. case statements as well as if-then-else).
