May I ask one question related to the Target Usage Requirements ...
For HDF5 (for example), the user might enable Parallel IO, which requires MPI.
When enabled, the hdf5 cmakelists use find_package to get MPI and all is fine.
Users of hdf5 might not know that they are using an hdf which has
One important extra point.
The MPI library was NOT built with cmake, but the HDF5 and the user's project
would be. Not sure if that makes a difference

Sorry, I assumed too much familiarity with hdf5/mpi
Hdf5 has CMakelists.txt files and declares a number of targets. When built with
parallel IO, hdf5 used find_package(MPI) to get the required libs and includes
for the library to compile and link nicely with mpi. No problem

OK. I can add the find_package to the hdf5-config.cmake
But the user still has to add the include path to their own projects, and link
each target against mpi.
Paraview, for example, fails to build when you link against a system hdf5 which
has parallel enabled. You have to

This is what I was advised not to do before.

Understood. This seems sensible.

Suppose hdf5 pulls in the mpi lib and includes, and the project using it

sure the user does not choose a different mpi lib
I'm not aware of a standard way to deal with
