# Locate SimGear
|
|
# This module defines
|
|
# SIMGEAR_LIBRARIES
|
|
# SIMGEAR_FOUND, if false, do not try to link to SimGear
|
|
# SIMGEAR_INCLUDE_DIR, where to find the headers
|
|
#
|
|
# $SIMGEAR_DIR is an environment variable that would
|
|
# correspond to the ./configure --prefix=$SIMGEAR_DIR
|
|
# used in building SimGear.
|
|
#
|
|
# Created by James Turner. This was influenced by the FindOpenAL.cmake module.
