#  GANDIVA_IMPORT_LIB, path to libgandiva's import library (Windows only)
#  GANDIVA_INCLUDE_DIR, directory containing headers

#  GANDIVA_LIB_DIR, directory containing Gandiva libraries
#  GANDIVA_SHARED_IMP_LIB, deprecated. Use GANDIVA_IMPORT_LIB instead
#  GANDIVA_SHARED_LIB, path to libgandiva's shared library
#  GANDIVA_SO_VERSION, shared object version of found Gandiva such as "100"
