To build via VC++:
Original SDL libraries (make sure to download the VC development libraries):
These need to be referenced to CMake for libSDL2pp to pick them up. The SDL development libraries come with both 32-bit and 64-bit binaries so CMake needs to be also told which one of these should be used.
clone the libSDL2pp repo: https://github.com/libSDL2pp/libSDL2pp
Place the repo in a folder named extlib/libSDL2pp at the root of the project
cmake .. -G "Visual Studio 15 2017 Win64" -DSDL2PP_WITH_TTF=OFF -DSDL2PP_WITH_MIXER=OFF -DCMAKE_PREFIX_PATH="<your_SDL_folder>/SDL2;<your_SDL_folder>/SDL2_image" -DCMAKE_LIBRARY_ARCHITECTURE=x64
