FindVPR22.cmake

# - try to find VPR 2.2 library
# Requires Boost 1.33.1 or greater (including filesystem and signals libraries)
# (and thus FindBoost.cmake from 2.8rc3 or newer, preferably)
# Requires NSPR4 (and PLC4) on Windows
# Requires pthreads on Unix (Mac or Linux)
# Requires libuuid on Linux
# Optionally uses Flagpoll and FindFlagpoll.cmake
#
# This library is a part of VR Juggler 3.0 - you probably want to use
# find_package(VRJuggler30) instead, for an easy interface to this and
# related scripts.  See FindVRJuggler30.cmake for more information.
#
#  VPR22_LIBRARY_DIR, library search path
#  VPR22_INCLUDE_DIR, include search path
#  VPR22_LIBRARY, the library to link against
#  VPR22_FOUND, If false, do not try to use this library.
#
# Plural versions refer to this library and its dependencies, and
# are recommended to be used instead, unless you have a good reason.
#
# Useful configuration variables you might want to add to your cache:
#  VPR22_ROOT_DIR - A directory prefix to search
#                   (a path that contains include/ as a subdirectory)
#
# 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.
#
# The VJ_BASE_DIR environment variable is also searched (preferentially)
# when searching for this component, so most sane 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.
