I have created a small test [1] that downloads and builds SDL2,  
installs it, and builds a little test program using SDL2. For  
cross-compiling, I am using the mingw-w64 [2] compilers provided in  
Debian GNU/Linux. I use the FindSDL2 module that I posted to this  
mailing list some time ago [3, 4]. This module has no problem finding  
the SDL2 installation:
-- Found SDL2: [… snip …]/cmake-FindSDL-test/install/include/SDL2  
(found suitable version "2.0.3", minimum required is "2.0.3")
Have you also installed SDL2, or did you try to find the build directory?

Kind regards
Benjamin
