I just recently caught one of these order of include paths in
gr-uhd/swig. Its so easy to accidentally get it in the wrong order. I'd
like to take a look: Can you say what component is pulling in the
installed headers? Is it a specific component, swig module, etc?

Also; There is also a little swig dependency searcher at the bottom of
GrSwig.cmake. I wrote this, and its got its flaws. If you configure,
uninstall some public headers, and try to build, you may get an error
until you reconfigure...
