Revert Orbiter to use Fetch mechanism instead of submodules

DarkWanderer commented 4 months ago

Reasons

Submodules are extremely messy - unlike plug-and-play CMake dependency management
There is already a mix of submodules and plain source commits indicating that contributors do not understand how to work with submodules

Change

Use Fetch_MakeAvailable instead of .gitmodules to avoid unnecessary complexity. Lua modules are out of scope for now

I plead guilty for adding plain source external dependencies, because adding submodules in pull requests seems a mess to synchronize between different repositories, especially when you do modifications to the original code.

If there's a simple way to do it then I'd be happy to hear it.

What is the use case for the changes in original code? Can it be covered by 'glue' code instead?

The ldoc module is generating CSS that looks terrible in htmlhelp, I patched some hard coded CSS values to work around it. There's probably a cleaner way to do it but I was running out of steam doing the documentation work and forgot to investigate it further.

That's not the best way to handle it generally - as it will make updating the modified library a sisyphean task later. It seems like time to fix that exceeds the time I have currently though, so I have limited the scope of the PR to elimination of submodules. Ready for review

A couple of remarks :

I don't know if the Lua github is the official one but it's not listing the latest 5.1.5 release. I tried to use
```
FetchContent_Declare(
lua
URL https://www.lua.org/ftp/lua-5.1.5.tar.gz
URL_HASH SHA256=2640fc56a795f29d28ef15e13c34a47e223960b0240e8cb0a82d9b0738695333
)
```
but as expected, like every other thing cmake related, I cannot make it work.

If I comment the #if(ORBITER_MAKE_DOC) to generate the Lua doc, the build fails :

Yes, the GitHub repo doesn't have 5.1.5 for some reason. Do we need that version specifically? Can we live with 5.1.1?

If I comment the #if(ORBITER_MAKE_DOC) to generate the Lua doc, the build fails :

Sounds like we need documents build enabled in CI... I'll take a look

TheGondos commented 3 months ago

Can we live with 5.1.1?

Yes it should be good enough for the time being

Regarding the documentation, it's not producing a pdf but still using htmlhelp to generate a .chm file.
