Hello Steffen,

It is most probably not necessary for any BSP to copy things to the
filesystem of your build host outside of the BSP working directory.

I just successfully built Qt5 with the options you mentioned (but
examples deactivated, which failed to build), so let me ask: is qt5
itself failing to build on your site or is it your own application
requiring qt5?

If the latter, could you please deactivate your app for once, to make
sure qt5 itself builds fine?  I suspect a problem with your app
setting the correct include paths.

I'm no expert on Qt5, but from what I could tell from the build
environment here: those files are not in the qt5 source tree, but
seem to be created in the build process.  I found those in 

- ./platform-v7a/build-target/qt-everywhere-src-5.15.0-build/qtbase/lib/metatypes/
- ./platform-v7a/packages/qt-everywhere-src-5.15.0/usr/lib/metatypes/
- ./platform-v7a/sysroot-target/usr/lib/metatypes/

Your app build should pick it up from sysroot-target, but that should
basically "just work", no need for setting absolute paths.  How this
is done depends on what kind of build system you use of course.  For
Qt5 based apps I would probably try CMake.

Correct, see above.
