Install Axom with RAJA on Windows

[tlorentz77]

Hi there,

Could you please update the port file of Axom in vcpkg to integrate RAJA lib?

It seems that RAJA can be build on Windows with capability of OPENMP now.

@tlorentz77 -- our vcpkg can now build RAJA with OpenMP on Windows through uberenv

Thank you @kennyweiss and sorry for the late feedback. I successfully build axom based on vcpkg now, but failed to search the axom using find_package. It reports that there is no camp-config.cmake file in the direcotry. The reason is that the PATHS provided in file axom-config.cmake.in (as shown in the follow) is not compatible with vcpkg. In vcpkg the package config files like xxxx-config.cmake are usually in directory like xxx/share/camp. So I think the file axom-config.cmake.in should be update as well if we want to use axom as TPL on Windows platform.

  if(AXOM_USE_CAMP)
    set(AXOM_CAMP_DIR      "@CAMP_DIR@")
    if(NOT CAMP_DIR) 
      set(CAMP_DIR ${AXOM_CAMP_DIR})
    endif()
    find_dependency(camp REQUIRED NO_DEFAULT_PATH PATHS "${CAMP_DIR}/lib/cmake/camp")
  endif()

Could you please provide an axom-project-template just like RAJA-project-template (https://github.com/LLNL/RAJA-project-template)? It would be helpful for users who are not familiar with axom. Thank you very much!

Thanks @tlorentz77 -- We currently build and test axom+raja+umpire+openmp+mfem+conduit using vcpkg (through uberenv), but have not yet taken the next step of importing that axom into another project.

We have similar examples to the RAJA-project-template in axom/src/examples/using-with-{blt,cmake,make} -- https://github.com/LLNL/axom/tree/develop/src/examples -- and describe them in our Quickstart guide -- https://axom.readthedocs.io/en/develop/docs/sphinx/quickstart_guide/zero_to_axom.html

Our unix-based CI exercises the using-with- examples, but our Windows CI does not. I'll create a new issue to fix this and to add it to our Windows CI.

Thanks very much. @kennyweiss

Hello @kennyweiss , thanks for your help. However I still failed to import Axom as a TPL on Windows after a few days of work. It would be appreciated if you can create a new issue to add the example.

Thanks for the reminder @tlorentz77.

I created #1028 to track this.
