Compiling error.

Hello,

I've tried compiling your project on Arch Linux, but was met with a SDL.h: No such file or directory error.

Here's the CMake output:

CMake Deprecation Warning at CMakeLists.txt:1 (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.

Hi, the code needs SDL2, SDL_gpu, SDL2_ttf and pixman to compile.

The way I used it I had a top-level CmakeLists.txt which included all of the other dependencies first, for which I've downloaded the source code manually, and then at the end included this project.

This means that it currently does not find the sources if you installed them via the system package manager, I will try to improve that.

Hello,

Thank you for your answer.

I was only missing SDL_gpu, but installing it didn't help and the compiling error is still the same.

[Abestanis]

Can you please let me know if the changes from #42 would allow you to compile.
