Code uses 4 libs (fftw-3.3.8, libsndfile-1.0.28, libssh and nlohmann-json). The issues are:
--filesystem is different in mac and ubuntu
- file streaming issues on Linux
-nlomhamon json only works on c++11
-lstdc++fs only works for c++17
I need exact details on what you did to get the code to compile and the solution.
