Summary

Bug 215650

[swills]

The components list seems to match up with Mk/Uses/lxqt.mk and the content looks fine to me.

It's probably best to explicitly say "commonly used components" to be clear about what these values are.

I don't understand what this entry is -- is it helpers *for* additional CMake modules, or additional CMake modules that are helpful, or ...?

Avoid the aside: "...below and also documented..." (and remember to remove the closing paren) (yes that's an aside, and this one too)

Try to avoid if/then sentences. Occasional use is okay, but still, try to avoid. Often just rearranging them gets rid of the if/then and pause:

Below, it just says "Available LXQt Components". Isn't that all of them? If it is, this can just say "...a list of needed components from the table below."

Addressed the remaining two points.
