Make Optional26 Packageable

[bretbrownjr]

I attempted to add Optional26 to the Conan local recipe index I am finishing up in bemanproject/beman#21.

Two problems (so far):

• Optional26 needs tarball and/or zip releases.
• Optional26 uses CMakeLists.txt that assumes dependencies, at least googletest are vendored into the repo via git submodule workflows

The first issue can be fairly trivially resolved by clicking using the release feature in the github.com web UI and cutting a release. Of course, an established process and even CI for this task would be great, including developing patterns and CI scripts that other beman projects could benefit from.

The second issue could be a matter of making the relevant add_subdirectory conditional somehow, using find_package workflows instead and adding googletest as a package dependency in Conan to ensure it's available to build against. It's also possible that using FetchContent instead of git-submodules would make the packaging "work", but Conan is designed such that it does source code indexing and fetching, so I would prefer to adhere to that design when using Conan.

Hello @bretbrownjr !

The first issue can be fairly trivially resolved by clicking using the release feature in the github.com web UI and cutting a release. Of course, an established process and even CI for this task would be great, including developing patterns and CI scripts that other beman projects could benefit from.

I propose to discuss on Monday in the Beman sync. I think we should have an unified approach (including scripts, CI jobs) for releases in Beman Project. Do we have a script or a CI job for Beman.Example?

The second issue could be a matter of making the relevant add_subdirectory conditional somehow, using find_package workflows instead and adding googletest as a package dependency in Conan to ensure it's available to build against. It's also possible that using FetchContent instead of git-submodules would make the packaging "work", but Conan is designed such that it does source code indexing and fetching, so I would prefer to adhere to that design when using Conan.

I created #29 29. Does this help as an intial step?

@bretbrownjr , #29 was merged. I think we need to update the issue description.
