You'll have to use separate directories for the two libraries.  Using 
LIBRARY_OUTPUT_PATH you can get them to still show up next to each other 
in the build tree.  The source files can also stay next to one another 
because you can specify a relative path to them in the CMakeLists.txt file.

Per-target include directory (among other) settings would be a good 
feature request for the bug tracker if you want to add it:
