blisp uses few submodules (libserialport, argtable). Many distributions already package those. Likely, blips does not plan any custom patches in those.

It would be convenient enhancement to allow -- at least optionally (CMake define) -- using any prepackaged system libraries, using e.g. cmake/pkgconfig mechanisms to check for existence of required version. Providing this may ease source based distribution, and may also benefit previous topics like issue #5 or issue #32 .
