Can't install qtquickdesigner-components on Qt creator 7.0.0

[ing-s]

Hello Qt Forum,

I'm trying to install qtquickdesigner-components on this Qt creator Version:

In this OS: Ubuntu 20.04.4 LTS

After cloning from official repo...

~/Qt$ git clone "https://codereview.qt-project.org/qt-labs/qtquickdesigner-components"

I followed this steps in https://doc.qt.io/qtdesignstudio/quick-converting-ui-projects.html but failed:

• Results in errors:

~/Qt/qtquickdesigner-component$ /home/user/Qt/6.2.4/gcc_64/bin/qmake -r

• This needs CMake 3.20 version that's not available for installing quickly on ubuntu(the actual version is 3.16).

~/Qt/qtquickdesigner-components$ cmake -GNinja -DCMAKE_INSTALL_PREFIX=~/Qt ~/Qt/qtquickdesigner-components

Tried with cmake 3.23 and this are the results:

user@user:~/Qt/qtquickdesigner-components$ /home/user/cmake3.23/bin/cmake -GNinja -DCMAKE_INSTALL_PREFIX=~/Qt ~/Qt/qtquickdesigner-components

CMake Error: CMake was unable to find a build program corresponding to "Ninja". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.

CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage

CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!
See also "/home/user/Qt/qtquickdesigner-components/CMakeFiles/CMakeOutput.log".

Thi is the CMakeOutput.log;

The system is: Linux - 5.13.0-37-generic - x86_64

I think that the documentation is not updated in this case for Ubuntu 20.04 LTS, How can i achieve this to use it?

@ing-s I found to go to the next step. when you clone the repo dev branch is setting by default, you need to change the branch to qmake just executing this:

user@user:~/Qt/qtquickdesigner-components$ git checkout qmake

But when you execute
user@user:~/Qt/qtquickdesigner-components$ /home/user/Qt/6.2.4/gcc_64/bin/qmake -r

This error show you:

/home/user/Qt/6.2.4/gcc_64/lib/libQt6Core.so -lpthread -lxkbcommon -lGL   
/usr/bin/ld: no se puede encontrar -lxkbcommon
collect2: error: ld returned 1 exit status

@ing-s The next step is just search the missing library
-l<library-name> and search through apt command, install the dev package and execute make again:

user@user:~/Qt/qtquickdesigner-components$ apt search xkbcommon
user@user:~/Qt/qtquickdesigner-components$ sudo apt install libxkbcommon-dev
user@user:~/Qt/qtquickdesigner-components$ make
user@user:~/Qt/qtquickdesigner-components$ make install

And done for anyone who see this.
