How do I merge pthread.cpp with codec? #4

I wonder what are pthread.cpp and semaphore.cpp for? I compiled the add-ons in C++11 and was unable to merge the codec. I had to use libpthread. Is that good thinking?

uvg266 uses pthreads, which is present in any Unix based platform (including MinGW and derivatives) but not on native Windows which is why we created https://github.com/ultravideo/ThreadWrapper as a minimal implementation of pthreads so that we no longer needed a third party dependency to a pthreads library.

If you are on Unix based system you should use the platform supplied pthreads.

In practice we have only used our built-in pthread wrapper with visual studio like the CMakeLists.txt does currently: https://github.com/ultravideo/uvg266/blob/master/CMakeLists.txt#L119

I already know what I didn't know. I used c11. Should be c++11 for library merge
