[Interest] QPA display system query ?

[Nicholas Yue]

Thanks Thiago.

On Windows and Mac, there are corresponding windeployqt and macdeployqt

On *nixes, there is linuxdeployqt but that didn't work for me as it
requires very specific glibc, the author of linxudeployqt have their
legitimate reason for being very specific about runtime for their tool to
work.

So I have to mimic the deployment as best as I can with regards to the QPA
for display as that done in windowsdeployqt and macdeployqt so I have
something like the following

install(FILES
  ${QT_INSTALL_PLUGINS}/platforms/libqxcb.so
  DESTINATION
  bin/platforms
  )

I was hoping to factor out the hard coding of xcb in the above which I can
query.

So yes, it is like an XY problem.

Happy to hear of proper CMake way to install the required QPA for a
software to be package up and ship to user without shipping the entire Qt
6.0.0 build on the Linux platform.

Cheers
