#  Try to find the UVCCameraControl library to manipulate webcam via USB on OS X
#
#  You must provide a UVCCAMERACONTROL_ROOT_DIR which contains lib and include directories
#
#  Once done this will define
#
#  UVCCAMERACONTROL_FOUND - system found UVCCameraControl
#  UVCCAMERACONTROL_INCLUDE_DIRS - the UVCCameraControl include directory
#  UVCCAMERACONTROL_LIBRARIES - Link this to use UVCCameraControl
