OpenXcom requires a vanilla version of the original UFO: Enemy Unknown / X-COM: UFO Defense (any edition) with the latest patch. It is not compatible with other games in the X-COM series. If you don’t own a copy, you can buy it from one of these retailers.
Do not use modded versions of X-COM, as they may be incompatible with OpenXcom.
Check the Installation documentation for more details.
These builds are automatically generated from the codebase, so they have the latest fixes and updates as well as the latest bugs. Use these to try the latest features or check if a bug is obsolete. Do not install these on top of 1.0!

treat third-party include files as system includes
this prevents gcc and clang from showing warnings about code that we can
do nothing about. in particular, this gets rid of the warning about the
multiple definitions of GL_GLEXT_VERSION in both SDL_opengl.h and
glext.h.
