Thank you for your quick reply. Before I dig deeper I first wanted to
check whether other people have already encountered this "archive flag /
cannot re-generate source files with cmake" issue as well, or whether
this is just "how cmake is supposed to work" (-> also clear the cmake
"configuration / build files" before a complete rebuild).

And sorry if this is getting off-topic (I am aware that this is possibly
more a cmake related question than Qt), but since cmake is (going to be)
the default build system in Qt 6 (replacing good ol' qmake *sniff* ;)) I
thought it may be worthwile to ask here.

Yes, I initially was also suspecting some "rogue cmake process" which
was still holding "locks" on certain build files. But checking in the
process monitor ("Task Manager") I did not find any suspicious process
after a build had completed (related to cmake) - at least not my name
(no running / sleeping process had "cmake" in its name).

I can live with the fact that I also need to clear the cmake project
files, as "rebuilding from scratch" is not something that I do regularly
(more so in order to check whether the project "still builds from
scratch"), so I am not inclined to dig any deeper for now. Unless
someone stumbled over the same issue...

And yes, I intend to "outsource" the Windows specific code into a plugin
which is optionally build (= only on Windows, obviously), so I can
switch my "main development" back to Mac / Linux ;)


Many thanks & Happy New Year!
