Well, yes. That gets the source files recognized properly. But I'm
still having some trouble in getting references to the source
directory to get resolved properly. I need to add an include path
relative to the source dir:

INCLUDES += $(dir src)

will when compiling stuff in src resolve to "." and ../Legacy. I need
them to resolve to the source directory. If the build directory is

   build-dir/Debug/Project/src

and the source directory is

  Project/src

I need them to resolve to

  ../../../../Project/src

I can fix this by setting

  SOURCE_DIR=$(dir .)

in the top-level OMakefile, and

  INCLUDES += $(dir $(SOURCE_DIR)/Project/src)

in Project/OMakefile, but it would be nice if there was a more elegant solution.
