*.cmake files are installed in a not standard cmake directory

[matzeri]

Describe the bug
Building on Cygwin hdf5-2.0.0 the *.cmake files are installed in a not standard cmake directory

/usr/cmake/hdf5-config-version.cmake
/usr/cmake/hdf5-config.cmake
/usr/cmake/hdf5-targets-relwithdebinfo.cmake
/usr/cmake/hdf5-targets.cmake

Expected behavior
All other packages are installed in subdirectory under /usr/lib/cmake, so it should be

/usr/lib/cmake/hdf5/hdf5-config-version.cmake
/usr/lib/cmake/hdf5/hdf5-config.cmake
/usr/lib/cmake/hdf5/hdf5-targets-relwithdebinfo.cmake
/usr/lib/cmake/hdf5/hdf5-targets.cmake
