# - Try to find GMTL
# Optionally uses Flagpoll and FindFlagpoll.cmake
# Once done, this will define
#
# GMTL_FOUND - system has GMTL
# GMTL_INCLUDE_DIR - the GMTL include directory
#
# Useful configuration variables you might want to add to your cache:
# GMTL_ROOT_DIR - A directory prefix to search
# (a path that contains include/ as a subdirectory)
# GMTL_ADDITIONAL_VERSIONS - Additional versions (outside of 0.5.1 to 0.7.0)
# to use when constructing search names and paths
#
# This script will use Flagpoll, if found, to provide hints to the location
# of this library, but does not use the compiler flags returned by Flagpoll
# directly.
#
# VR Juggler requires this package, so this Find script takes that into
# account when determining where to search for the desired files.
# The VJ_BASE_DIR environment variable is searched (preferentially)
# when searching for this package, so most sane VR Juggler build environments
# should "just work." Note that you need to manually re-run CMake if you
# change this environment variable, because it cannot auto-detect this change
# and trigger an automatic re-run.
