How to install Qt from the command line?

HoliGui

Hi,
I'm running Ubuntu 22.04, and I would like to install Qt6 but via the console and not the installer.

I found this packages:
sudo apt-get install build-essential
sudo apt-get install qtcreator
sudo apt install qt6-base-dev

But when i want to build my project I get following errors:

CMake Error at /usr/lib/x86_64-linux-gnu/cmake/Qt6/QtFeature.cmake:1212 (message):
  Feature rpath is already defined to be "ON" and should now be set to "OFF"
  when importing features from Qt6::Core.

This is how my cmake file works:

set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_PREFIX_PATH "/usr/lib/x86_64-linux-gnu/cmake")

find_package(QT NAMES Qt6 REQUIRED COMPONENTS Widgets)
find_package(Qt${QT_VERSION_MAJOR} REQUIRED COMPONENTS Widgets)
find_package(Qt${QT_VERSION_MAJOR}Test REQUIRED)

set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)


find_package(MPI REQUIRED)
message(STATUS "Run: ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} ${MPIEXEC_MAX_NUMPROCS} ${MPIEXEC_PREFLAGS} EXECUTABLE ${MPIEXEC_POSTFLAGS} ARGS")
add_executable(...my source files)
target_link_libraries( target PUBLIC OpenMP::OpenMP_CXX Qt${QT_VERSION_MAJOR}::Widgets Qt${QT_VERSION_MAJOR}::Test MPI::MPI_CXX)

When I created the project I installed Qt via the GUI installer, and it worked fine, but that's not an option because I want to build my app via CI/CD on some alpine/ubuntu;
