NGA FY22: improve build system #128
Description
- Develop CMake build system to build all the KokkosTools
- Extent the tools cmake build system to optionally build Caliper and Apex (i.e. translate typical Kokkos
options such as Kokkos_ENABLE_CUDA to the respective settings for Caliper and Apex) - Add option to build all tools as a single library, and add an initialization interface to that library, which uses
the existing KokkosEventSet capability to load a specific tool in the library upon being called with the
corresponding option (e.g. KokkosTools::initialize("space_time_stack"));
