# Global variables:
#
# OPENCV_MODULE_${the_module}_LOCATION
# OPENCV_MODULE_${the_module}_DESCRIPTION
# OPENCV_MODULE_${the_module}_CLASS - PUBLIC|INTERNAL|BINDINGS
# OPENCV_MODULE_${the_module}_HEADERS

# To control the setup of the module you could also set:
# the_description - text to be used as current module description
# OPENCV_MODULE_TYPE - STATIC|SHARED - set to force override global settings for current module
# OPENCV_MODULE_IS_PART_OF_WORLD - ON|OFF (default ON) - should the module be added to the opencv_world?
# BUILD_${the_module}_INIT - ON|OFF (default ON) - initial value for BUILD_${the_module}

#
# ocv_add_module(modname <dependencies>)
# ocv_glob_module_sources(([EXCLUDE_CUDA] <extra sources&headers>)
