Result Variables ^^^^^^^^^^^^^^^^ This will define the following variables: ``OpenVDB_FOUND`` True if the system has the OpenVDB library. ``OpenVDB_VERSION`` The version of the OpenVDB library which was found. ``OpenVDB_INCLUDE_DIRS`` Include directories needed to use OpenVDB. ``OpenVDB_LIBRARIES`` Libraries needed to link to OpenVDB. ``OpenVDB_LIBRARY_DIRS`` OpenVDB library directories. ``OpenVDB_DEFINITIONS`` Definitions to use when compiling code that uses OpenVDB. ``OpenVDB_{COMPONENT}_FOUND`` True if the system has the named OpenVDB component. ``OpenVDB_USES_BLOSC`` True if the OpenVDB Library has been built with blosc support ``OpenVDB_USES_LOG4CPLUS`` True if the OpenVDB Library has been built with log4cplus support ``OpenVDB_USES_EXR`` True if the OpenVDB Library has been built with openexr support ``OpenVDB_ABI`` Set if this module was able to determine the ABI number the located OpenVDB Library was built against. Unset otherwise. Cache Variables ^^^^^^^^^^^^^^^ The following cache variables may also be set: ``OpenVDB_INCLUDE_DIR`` The directory containing ``openvdb/version.h``. ``OpenVDB_{COMPONENT}_LIBRARY`` Individual component libraries for OpenVDB Hints ^^^^^ Instead of explicitly setting the cache variables, the following variables may be provided to tell this module where to look. ``OPENVDB_ROOT`` Preferred installation prefix. ``OPENVDB_INCLUDEDIR`` Preferred include directory e.g. /include ``OPENVDB_LIBRARYDIR`` Preferred library directory e.g. /lib ``SYSTEM_LIBRARY_PATHS`` Paths appended to all include and lib searches. #]=======================================================================] #
