How to compile for Linux?

[shitpoet]

I was trying cmake . and then make but I've get a lot of errors:

Output of cmake ., everything seems good:

$ cmake .
CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 2.8.12 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.

But output of make is full of problems in the linking stage:
