Sure.

1.  I had originally referenced the online installer as it is front and centre on the Qt site.  The LC wiki instructions I pulled this from explicitly recommended the offline installer, and yes, I did have to dig for it.  And, it's a big download since everything is included.  I've used both and the online installer worked almost identical to the offline installer, even using the windows "Add/Remove Programs" dialog to reconfigure.  I'm a little suprised to Doug had to locate additional downloads. I didn't mention it as I didn't need to find any further downloads - one or two checkmarks on the Select Components page was all that was required.  That may be a problem with having to dig for a download of the offline installer on the Qt site.  I'm happy to change it back to the open-source online version as it is shown on the main dowload page.

MinGW is shown as a required component:
   "On the Select Components page include the latest version of the compiler, MinGW, under the most recent version of Qt, e.g. MinGW 7.3.0 32-bit and Qt 5.12.3 respectively."

Is there something else missing for building in Qt?

2.  It is a FYI.  It is mentioned as a dependency common to all they OSeses.  Those  that are more observant might wonder if it is not mentioned, but I doubt it.

3.  I added a note with a link in the appendix specifically mentioning building on VS 2013 and later to the  Build from source instructions.

A single command line script to do the whole thing would be easier.  The LC wiki build instructions does offer a script to build a package , but required a bunch of editing.
