Hello Community,

Disclaimer: I repost this here from the official Qt Forum, as I didn't get answer there.

I am trying to deploy a Qt program using the qt_generate_deploy_app_script command and pack it up as RPM according to the instructions here: https://www.qt.io/blog/deploying-to-linux-with-cmake.

It seems to me, that the Qt deployment script does not work with the changed destination for installing, that is set by cpack.

I added a minimal program that illustrates the problem below. I am using Qt 6.7.2 on RHEL 9.2.

Thanks for any help,
Ralf

Steps to reproduce:

Qt Code: 
  1. mkdir build
  2. cd build
  3. ~/Qt/Tools/CMake/bin/cmake -DCMAKE_PREFIX_PATH=~/Qt/6.7.2/gcc_64/ ..
  4. make
  5. make package

main.cpp

Qt Code: 
  1. #include <QDebug>
  2. #include <QApplication>

  4. int main(int argc, char *argv[]) {
  5.     QApplication app(argc, argv);
  6.     qDebug() << "Hello World";
