[Interest] Issue building Qt from source

[Sean Murphy]

Yesterday I built Qt 6.3.2 from source (using qt-everywhere-src-6.3.2.zip) on Windows and had a couple snags.

I'm not trying to customize anything, so first attempt I just did:
  configure.bat
  cmake --build . --parallel
  cmake --install .
All of those completed without errors, but when I compiled my first application, it built fine in debug mode, but couldn't link in release mode. I looked in C:\Qt\6.3.2\bin and sure enough, only debug versions of the Qt DLLs were present. I dug around in my Qt build directory and could only find debug versions of the DLLs there too.

So I cleaned out my build directory and modified my configure line to include "-debug-and-release" like so:
  configure.bat -debug-and-release
  cmake --build . --parallel
Once again it built fine. I checked my Qt build directory (under qtbase for example) and verified that indeed both the debug and release versions of the DLLs were built. Then I executed the install command
  cmake --install .
This time, only the release versions of the DLLs were copied up into C:\Qt\6.3.2\bin, the debug versions didn't get copied over. I manually copied them over, and then I was able to build my application in either release or debug builds.

Did I miss something in the installation instructions? Or is this a bug in the build script?
