CMake warning calling find_package(DDC)

[tpadioleau]

The CI reports this kind of warning:

CMake Warning (dev) at /usr/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:438 (message):
  The package name passed to `find_package_handle_standard_args`
  (Kokkos_DEVICES) does not match the name of the calling package (DDC).
  This can lead to problems in calling code that expects `find_package`
  result variables (e.g., `_FOUND`) to follow a certain pattern.
Call Stack (most recent call first):
  /data/opt/kokkos/lib/cmake/Kokkos/KokkosConfigCommon.cmake:110 (find_package_handle_standard_args)
  /data/opt/ddc/lib/cmake/DDC/DDCCheckRequiredKokkosOptions.cmake:6 (kokkos_check)
  /data/opt/ddc/lib/cmake/DDC/DDCConfig.cmake:44 (ddc_check_required_kokkos_options)
  CMakeLists.txt:9 (find_package)
This warning is for project developers.  Use -Wno-dev to suppress it.

It comes from the kokkos_check macro that calls find_package_handle_standard_args.

@EmilyBourne Do you find it annoying ? I should be able to workaround this on the DDC side.

[EmilyBourne]

I'm not sure I'm the right person to ask. I have not noticed this message on my laptop.

I have just recompiled and it does not appear locally.

[tpadioleau]

It will appear after updating DDC to version 0.4

[EmilyBourne]

Ah, then this is likely to annoy me. But not enough to complain about it. It's up to you depending on how easy/hard your workaround is.

[tpadioleau]

It can be removed actually, it is just a helper to diagnose in case there is a problem when an environment has multiple kokkos.
