# CMake configuration for HDF5 parallel test library and test executables
# This file sets up the build, formatting, and installation rules for the HDF5 parallel test library (static/shared) and its test executables.
# It handles source/header definitions, compiler options, linking, export, and test configuration for parallel HDF5 testing.
