Dear Leo,

I had another look at those libraries:

those can be removed, they are already included in ‘inputs’ and the 
configure script favours the system (guix) lib over them.

The remaining three libraries are referenced directly from the source
code. Here are comments from README.md:

--8<---------------cut here---------------start------------->8---
A class, `utf8_codecvt_facet`, derived from `std::codecvt<wchar_t, char>`,
which can be used to convert utf8 data in files into `wchar_t` strings
in the application.

The other two are some ancient and orphaned libraries for deprecated
video formats, however GPLv2/LGPLv2.1:

Reading and writing avi files.

librmff is short for 'RealMedia file format access library'. It aims
at providing the programmer an easy way to read and write RealMedia
files.

Is it ok to just include them and adding those two licenses the package?

Best,
Gregor
