You mean the highest level? Maybe you visualize trees upside-down from
how I do it, but you're asking about integrating both pyProject and
cProject from the directory that houses both of those directories,
right?

Investigate add_subdirectory. From the top level, you do
add_subdirectory(pyProject) and add_subdirectory(cProject). Then you
have access to the targets defined in each, and your C targets can
depend on your python targets (or whatever).
