#
# CMake script for finding RTNet.
# If the optional RTNET_ROOT_DIR environment variable exists, header files and
# libraries will be searched in the RTNET_ROOT_DIR/include and RTNET_ROOT_DIR/lib
# directories, respectively. Otherwise the default CMake search process will be
# used.
#
# This script creates the following variables:
#  RTNET_FOUND: Boolean that indicates if the package was found
#  RTNET_INCLUDE_DIRS: Paths to the necessary header files
#  RTNET_LIBRARIES: Package libraries
