Configure and install version file when building in Trilinos

[aprokop]

This is a fix to install version file to address the missing part in #2779.

Can one of the admins verify this patch?

OK to test

@bartlettroscoe please confirm this is the right way to deduce the destination

This looks like the correct location.

NOTE: As I mentioned here, TriBITS may need to create this file as well in order to prefer finding "standard compliant" packages.

[bartlettroscoe]

When building inside of Trilinos, the various <Package>Config.cmake files get generated automatically. There should be no code in Kokkos itself that does this.

NOTE: We will be updating what these <Package>Config.cmake files look like as part of TriBITSPub/TriBITS#63 and TriBITSPub/TriBITS#299. The plan is to devote a lot of time starting in May to that work.

We are also working on a standard for these <Package>Config.cmake files in:

• https://gitlab.kitware.com/snl/project-1/-/issues/139

@bartlettroscoe this is not doing anything with KokkosConfig.cmake it only adds a Version.cmake file

@dalg24, can you contact me offline and I will see about getting you access to that site?

@crtrott, okay. But as part of addressing TriBITSPub/TriBITS#63, we may need to write a specialized <Package>ConfigVersion.cmake file to get that system to work (to differentiate standard compatible packages from non-standard compatible packages).

I can confirm that this works.

This looks fine as a fix for now.

Another argument for Trilinos as a TPL (see TriBITSPub/TriBITS#63) and kokkos as a TPL as well. SCALE/VERA/MPACT (for example) can't use on any projects that require also require Trilinos or Kokkos.
