How to install SDL dev library so CMake can find it

I'm running Windows and I want to install the SDL development files in a place so that find_package(SDL) works.

Should I include part of it in the PATH or what?

EDITS: I created the environment variable SDLDIR and set it to the directory containing lib/ and include/

Cmake output:

cmake -G "Visual Studio 12 2013 Win64" ..
-- The C compiler identification is MSVC 18.0.31101.0

I read a bit on the wiki page and found a slight workaround. I don't think it's perfect but it's fine for now.

cmake -G "Visual Studio 12 2013 Win64" -D SDL_LIBRARY_TEMP=%SDLDIR%\lib\x64\SDL2.lib ..

This correctly find SDL2 although I am running into another issue, but I will make a new topic for it.

Check the documentation and source of the CMace module that is supposed to find your package

FindSDL.cmake contains the following documentation comment:

# $SDLDIR is an environment variable that would correspond to the
# ./configure --prefix=$SDLDIR used in building SDL.  l.e.galup 9-20-02
