I see why this doesn't work now. LLDB plugins are added to the `LLDB_PLUGINS`
global property via the PLUGIN argument to `add_lldb_library`. You aren't
adding the PLUGIN argument to the `add_lldb_library` invocation in
`lldb/source/Plugins/ScriptInterpreter/Python/Interfaces/CMakeLists.txt`. This
is how the build system knows the list of plugins.
But even if you were to remove this and add that `PLUGIN` argument, this still
wouldn't work. I don't think we've explicitly documented this behavior, but
LLDB expects each library to be one plugin, not three as you've done here. When
LLDB creates a plugin, it's going to generate a `Plugins.def` file that LLDB
uses to initialize and teardown all plugins. It has a list of entries that look
like this:
`LLDB_PLUGIN(lldbPluginFooBar)`. There are some exceptions for the script
interpreter plugins (not sure why, didn't check). It also expects the
`LLDB_PLUGIN_DEFINE` argument to match the library name exactly (without the
initial `lldbPlugin`, specifically).
The way I see it, you have three options:
1. Restructure the build so that there are 3 libraries, each one of them a
plugin.
2. Change LLDB's CMake machinery to accept libraries that define multiple
plugin interfaces. You'll need to modify `add_lldb_library` so that you can
pass it a list of plugin interface names instead of assuming the plugin names
matches the library's name.
3. Keep the workaround and document why it exists.
I would suggest (1) or (2). I think (3) is just kicking the can down the road.
This is a solution that explicitly works around LLDB's existing plugin system,
is difficult to discover without knowing its there, and could make future
refactors more difficult.
