Just a word of caution: you can't simply use ExternalProject_Add and then
use FindPackage within the same CMakeLists.txt file for a plain old ParaView
build. You'd have to do a "super build" approach where both HDF5 and
ParaView are built as ExternalProject_Add calls and then ParaView could use
FindPackage to find the (configured/built/installed by previous build steps)
HDF5.

You could do ExternalProject_Add to build HDF5 as long as everything that
FindPackage currently sets gets set in a predictive fashion (*before* HDF5
itself is downloaded, configured, built or installed...)


Just thinking out loud, too,
