Locate ENET library
|
|
|

This module defines:
|
|
|
|
::
|
|
|
|
ENET, the name of the target to use with target_*() commands
|
|
ENET_LIBRARIES, the name of the library to link against
|
|
ENET_INCLUDE_DIRS, where to find the headers
|
|
ENET_FOUND, if false, do not try to link against
|
|
ENET_VERSION_STRING - human-readable string containing the
|
|
version of ENET
|
|
|
|
$ENETDIR is an environment variable that would correspond to the
|
|
./configure --prefix=$ENETDIR used in building ENET.
