# - Locate SDL2_net library
|
|
2 |
# This module defines:
|
|
3 |
# SDL2_NET_LIBRARIES, the name of the library to link against
|
|
4 |
# SDL2_NET_INCLUDE_DIRS, where to find the headers
|
|
5 |
# SDL2_NET_FOUND, if false, do not try to link against
|
|
6 |
# SDL2_NET_VERSION_STRING - human-readable string containing the version of SDL2_net
|
|
7 |
#
|
|
8 |
# For backward compatiblity the following variables are also set:
|
|
9 |
# SDL2NET_LIBRARY (same value as SDL2_NET_LIBRARIES)
|
|
10 |
# SDL2NET_INCLUDE_DIR (same value as SDL2_NET_INCLUDE_DIRS)
|
|
11 |
# SDL2NET_FOUND (same value as SDL2_NET_FOUND)
|
|
12 |
#
|
|
13 |
# $SDL2DIR is an environment variable that would
|
|
14 |
# correspond to the ./configure --prefix=$SDL2DIR
|
|
15 |
# used in building SDL2.
|
|
16 |

# Created by Eric Wing. This was influenced by the FindSDL2.cmake
|
|
18 |
# module, but with modifications to recognize OS X frameworks and
|
|
19 |
# additional Unix paths (FreeBSD, etc).
