CMake dependency error

[untereiner]

Hello,

I am trying to compile.
I have compiled fesapi dev branc with it's own hdf5 dependency
I have compiled paraview with
cmake -GNinja -DCMAKE_BUILD_TYPE=Release -DPARAVIEW_QT_VERSION=5 -DVTK_QT_VERSION:STRING=5 -DVTK_MODULE_USE_EXTERNAL_VTK_zlib:BOOL=ON -DVTK_MODULE_USE_EXTERNAL_VTK_hdf5:BOOL=ON -DHDF5_DIR:PATH=/path/to/f2i-consulting/fesapi-superbuild/install/release-gcc/hdf5/share/cmake/hdf5 ..
Then for fespp:
cmake -DFESAPI_ROOT:PATH=/path/to/f2i-consulting/fesapi-superbuild/install/release-gcc/fesapi -DParaView_DIR:PATH=/path/to/f2i-consulting/paraview/build/lib/cmake/paraview-5.12/ ..

I have an error at configure step:

CMake Error at /path/to/f2i-consulting/paraview/build/lib/cmake/paraview-5.12/vtk/VTK-targets.cmake:810 (set_target_properties):
  The link interface of target "VTK::hdf5" contains:

    hdf5::hdf5

  but the target was not found.  Possible reasons include:

    * There is a typo in the target name.
    * A find_package call is missing for an IMPORTED target.
    * An ALIAS target is missing.

Call Stack (most recent call first):
 /path/to/f2i-consulting/paraview/build/lib/cmake/paraview-5.12/vtk/vtk-config.cmake:145 (include)
 /path/to/f2i-consulting/paraview/build/lib/cmake/paraview-5.12/paraview-config.cmake:77 (find_package)
  CMakeLists.txt:32 (find_package)

I think it might be related to F2I-Consulting/fesapi#344
Paraview (vtkHDF5) is looking for hdf5::hdf5 but fesapi is advertising HDF5::HDF5

Maybe not a fespp issue...
If I manually edit /path/to/f2i-consulting/paraview/build/lib/cmake/paraview-5.12/vtk/VTK-targets.cmake and replace hdf5::hdf5 by hdf5 I have fespp C++ compilation issues..

As discussed on another channel, we tend to think it is caused by a Paraview build configuration. The shared HDF5 library does not look to be honored by Paraview which rather uses its own VTK HDF5 library.
We still continue to test some other PV build configurations.
