build failure: include path for hdf5 is not passed from cmake to gcc

[angli232]

In Mac OS X, package manager MacPorts installs packages such as hdf5 in the dir of /opt. Although cmake could successfully find it, a typo in CMakeLists.txt prevents the corresponding include path from being passed to gcc. ${HDF5_INCLUDE_DIR} in CMakeLists.txt should be corrected to ${HDF5_INCLUDE_DIRS}.

Error message of the build failure:
