Compilation error

[APoniatowski]

I am getting the following while building on Arch linux when following the instructions:

$ cmake -DCMAKE_BUILD_TYPE=Release ..
CMake Deprecation Warning at CMakeLists.txt:2 (cmake_minimum_required):
  Compatibility with CMake < 3.5 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

I have forked it and working on resolving it. I managed to resolve this build error and there was another build error

Closed as PR is merged. Thanks for both report and fix.
