   4 # This module specifies the following variables:
   5 #  OPENEXR_INCLUDE_DIR
   6 #  OPENEXR_LIBRARIES

   8 #
   9 # Additionally the following more specialized variables are defined:
  10 #  OPENEXR_LIBRARY_DEBUG        debug library
  11 #  OPENEXR_LIBRARY_RELEASE      release library
  12 #
  13 #  You can control where this module attempts to locate libraries and headers:
  14 #
  15 #  OPENEXR_ROOT_DIR          look for headers in ${OPENEXR_ROOT_DIR}/include/OpenEXR
  16 #                            look for libs in    ${OPENEXR_ROOT_DIR}/lib
  17 #  OPENEXR_INCLUDE_DIR       look for headers in ${OPENEXR_INCLUDE_DIR}/OpenEXR
  18 #  OPENEXR_LIBRARY_DIR       look for libs in    ${OPENEXR_LIBRARY_DIR}
  19 #
  20 #  Note: Setting these variables will skip searching the system default paths.
