Can't build for GNU/Linux

[M-II-R]

Hello. (Excuse me for my English.) Thank you fro this project! I d'like to try it, but after installing all dependencies I can't build binaries on my system. I suppose this library is a bit obsolete. I tried to replace some dependencies with their older versions (fmt and spdlog), but it didn't work. How can I build this?

P. S.: I send my build script (PKGBUILD),
PKGBUILD.txt

make output
errors.txt

and some necessary files.
spdlog.patch
spdlog2.patch
spdlog3.patch
CMakeLists.txt
CMakePatch.patch
