mingw32-SDL is installed.  Looking at the FindSDL.cmake and the
CMAKE_FIND_ROOT_PATH directory I can see why it doesn't find it.  The
/usr/i686-pc-mingw32 directory has bin, lib, and sys-root.  In
sys-root/mingw, you have bin, include, lib, and share.  The FIND_PATH
in FindSDL.cmake is obviously not looking in
sys-root/mingw/include/SDL.  Has anyone used mingw, SDL and cmake on
Fedora?  I don't see how you can configure that to pass.

Why should it. You obviously have an incomplete root path in your toolchain
file. Please note that CMAKE_FIND_ROOT_PATH is a _list_. In your    
case, you must
add /usr/i686-pc-mingw32/sys-root/mingw.

You may also have to call include_directories() for all standard    
include paths
in your root paths.

Adding /usr/i686-pc-mingw32/sys-root/mingw isn't going to accomplish
anything as /include is not in the list that FindSDL.cmake is looking
at.  It is looking for /usr/include.  I tried it anyway and it still
doesn't find SDL.  I could modify FindSDL.cmake to make it work but my
goal is to make the program compile on a standard fedora system.

I cite myself: "You may also have to call include_directories() for  
all standard include paths in your root paths."
This may include adding the your include/SDL.

I admit that FindSDL is not using the latest technique of  
PATH_SUFFIXES the right way (should be include include/SDL  
include/SDL11 include/SDL12, and the PATHS list below should be much  
smaller then). Nevertheless, doing it right in the toolchain file will  
probably make it work.
You can also set the variable ENV{SDLDIR} in your toolchain file if  
you find that easier:
set ( ENV{SDLDIR} /my/path/to/include/SDL )
