Well, that does not necessarily proove anything. Native libSDL is 
located in /usr with all others system wide libraries, so it seems quite 
normal that cmake finds it here without requiring a "hint".

But what does your "i686-w64-mingw32-gcc -print-sysroot" displays ? It 
seems some symlinks were added when you compiled and/or installed mingw. 
Maybe some bad parameters when running "./configure" before building mingw ?

Yes it works, but it seems a better solution would be to remove the 
symlinks in your installation. I think your mingw directories are messep 
up. This is what I have :
