Added the tinfo to the library and it works like a charm Tested on arm arm64 amd64

If you need to get going, simply add tinfo to the library part of the CMakefile.txt. 3.9.5 has the same problem, the 3.8.5 ebuild does work for 3.9.5 too. I've just been too lazy to make a patch.
@Philippe: Thanks a lot - attaching patch
