[REQUEST] Please make an install rule

[VictorEijkhout]

"After the compilation is done, you will find the executable called entity.xc in the build/src/ directory. That's it! You can now finally run the code."

That took me 10 minutes to find. Would it be an idea to have an install( ... ) rule in the cmake setup?

Hi @VictorEijkhout. The reason there is no install rule is very simple -- the code produces no side-effects, no shared libraries or config files. It's just a single executable; and the way people use the executable is not universal. Some people copy the executable manually and run it as ./entity.xc, others (incl. myself) simply provide a full path: ../path/to/entity/build/src/entity.xc -input ....

That being said, I'll be happy to add an install rule, it's quite simple to do. What do you think would be the ideal default directory to install, something like ./bin (in case the user does not provide -D CMAKE_INSTALL_PREFIX?

Done in #131. @VictorEijkhout if you could try and verify that it works as expected -- I'll merge into master and make a new subrelease. Thanks for the suggestion!

[VictorEijkhout]

It works but it also produces a few unexpected utilities. If that's intended, go ahead and make a release.

This is not intended, but it's unavoidable if you're building all the dependencies in-tree, since Kokkos itself provides its own install rules. Note, that the recommended way of using Entity is by separately installing both Kokkos and ADIOS2.

It looks like separate install of kokkos does away with those kokkos executables. Thanks. This is a nice and clean install.
