[Bf-committers] Blender and SDL

[Campbell Barton]

Hi, just tested building with SDL, it needed some update - so be sure
to try r44850 or newer,

as for finding the latest SDL, you just need to point CMake to it.

# sdl
./configure --prefix=/opt/sdl13; make -j; make install

#blender, the find modules often check and environment variable
SDLDIR=/opt/sdl13 cmake ../blender


... or you can set the cmake vars manually on an existing
configuration, from my CMakeConfig.txt

SDLMAIN_LIBRARY:FILEPATH=/opt/sdl13/lib/libSDLmain.a
SDL_INCLUDE_DIR:PATH=/opt/sdl13/include/SDL
SDL_LIBRARY:STRING=/opt/sdl13/lib/libSDLmain.a;/opt/sdl13/lib/libSDL.so;-lpthread

This isn't special for SDL, it works the same way when pointing CMake
to any non-standard version of a lib (OpenEXR, Boost, libtiff... etc)
