| FindSDL_net |
| ----------- |
| |
| Locate SDL_net library |
| |
| This module defines: |
| |
| :: |
| |
| SDL_NET_LIBRARIES, the name of the library to link against |
| SDL_NET_INCLUDE_DIRS, where to find the headers |
| SDL_NET_FOUND, if false, do not try to link against |
| SDL_NET_VERSION_STRING - human-readable string containing the version of SDL_net |
| |
| |
| |
| For backward compatibility the following variables are also set: |
| |
| :: |
| |
| SDLNET_LIBRARY (same value as SDL_NET_LIBRARIES) |
| SDLNET_INCLUDE_DIR (same value as SDL_NET_INCLUDE_DIRS) |
| SDLNET_FOUND (same value as SDL_NET_FOUND) |
| |
| |
| |
| $SDLDIR is an environment variable that would correspond to the |
| ./configure --prefix=$SDLDIR used in building SDL. |
| |
| Created by Eric Wing. This was influenced by the FindSDL.cmake |
| module, but with modifications to recognize OS X frameworks and |
| additional Unix paths (FreeBSD, etc). |
