Cpack deployment error: file RPATH_SET that does not exist

Ralf_G

Hello Community,

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:

mkdir build
cd build
~/Qt/Tools/CMake/bin/cmake -DCMAKE_PREFIX_PATH=~/Qt/6.7.2/gcc_64/ ..
make
make package

The error is the following:

CMake Error at <HOME>/Qt/6.7.2/gcc_64/lib/cmake/Qt6Core/Qt6CoreDeploySupport.cmake:139 (file):
  file RPATH_SET given FILE
  "/usr/plugins/egldeviceintegrations/libqeglfs-emu-integration.so" that does
  not exist.

main.cpp

#include <QDebug>
#include <QApplication>

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

CMakeLists.cpp

cmake_minimum_required(VERSION 3.29.3)

project(helloworld VERSION 0.1 LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 17)

)
install(SCRIPT ${deploy_script})

set(CPACK_GENERATOR RPM)
include(CPack)

What did you set to change the output directory of your libs?
I'm having the same issue, can't change the output directory of the qt_generate_deploy_app_script. When I tried by setting CMAKE_INSTALL_LIBDIR, I get RPATH errors and can't make the package successfully.
