#  FindVisage.cmake
# 
#  Try to find the Visage controller library
#
#  You must provide a VISAGE_ROOT_DIR which contains lib and include directories
#
#  Once done this will define
#
#  VISAGE_FOUND - system found Visage
#  VISAGE_INCLUDE_DIRS - the Visage include directory
#  VISAGE_LIBRARIES - Link this to use Visage
