# Locate SimGear

# This module defines

|
# SIMGEAR_CORE_LIBRARIES, a list of the core static libraries
|
|
# SIMGEAR_LIBRARIES, a list of all the static libraries (core + scene)
|
|
# 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.
