FindCPPDOM.cmake

# - try to find CPPDOM library
# Optionally uses Flagpoll and FindFlagpoll.cmake
#
#  CPPDOM_LIBRARY_DIR, library search path
#  CPPDOM_INCLUDE_DIR, include search path
#  CPPDOM_LIBRARY, the library to link against
#  CPPDOM_CXX_FLAGS
#  CPPDOM_FOUND, If false, do not try to use this library.
#
# Useful configuration variables you might want to add to your cache:
#  CPPDOM_ROOT_DIR - A directory prefix to search
#                    (a path that contains include/ as a subdirectory)
#  CPPDOM_ADDITIONAL_VERSIONS - Additional versions (outside of 0.7.8 to 1.2.0)
#                               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.
