You do not need to add a module into gnuradio tree to make it usable in
grc. In a out-of-tree project, you just need to edit the module's xml
file properly(gr_modtool can take care of the CMakeFiles.txt) and then
install it to proper directory by `make install`. Then in grc you should
be able to see your out-of-tree module in the list.
