Compile errors from SDL2pp/external/libcpp_optional.hh

[AMDmi3]

/home/sebastian/local/cuda-workspace/sdl/extlib/libSDL2pp/SDL2pp/external/libcpp_optional.hh:82:72: error: ‘__T0’ was not declared in this scope

Since there's no mention of __T0 in SDL2pp code, I suspect this is namespace/macro pollution on your side.

What was weird, that I had to add /usr/include/SDL2 to include directories because SDL was looking for SDL_stdinc.h in /usr/include instead of /usr/include/SDL2.

You probably need to add ${SDL2PP_INCLUDE_DIRS} to your include_directories.

Hey!
I at last found what was causing error. I was including SDL2pp.hh in CUDA compile unit (*.cu file). When I moved include to regular *.cpp file problem disappeared.
