# CMake configuration for HDF5 Java test suite
# This file sets up the build, and test execution rules for the HDF5 Java test suite.
# It handles Java test source grouping, JAR creation, test data management, test execution (including VOL tests),
# and integration with the HDF5 Java H5 and core libraries.
