Project ERROR: Unknown module(s) in QT: multimedia

I am trying to compile qGo, after installing qt5

git clone https://github.com/pzorin/qgo.git
cd qgo
qmake
make
sudo make install

Right now the latest error is saying it can't find multimedia

# make
cd src/ && ( test -e Makefile || /usr/lib/x86_64-linux-gnu/qt5/bin/qmake /home/jdm/Downloads/qgo/src/src.pro -o Makefile ) && make -f Makefile 
Project ERROR: Unknown module(s) in QT: multimedia
make: *** [sub-src-make_first] Error 3

I guessed the library libqt5multimedia5 based on this question, but the computer it says its already there and the error persists.

libqt5multimedia5 is already the newest version.

There is another similar question but the user answered his own question. I am not sure how it applies here:

I found that when I tried to build command line (i.e. qmake then make) I had a previous version (which qmake; qmake --version), and the Qt Creator has its own version installed when I installed Qt6. When I used the Qt6 explicit qmake, the issue was resolved:

$ [basepath]/Qt/6.6.1/gcc_64/bin/qmake

To resolve this issue on a Rocky 8 machine issue the following command:

sudo yum install qt5-qtmultimedia-devel

and install the requested package and its dependencies. The multimedia module should then be recognized.

I'm not able to post a comment, so I will write it as an answer. Your problem has been solved here: https://forum.qt.io/topic/27608/unknown-module-multimedia/6

In order to handle the issue you should try installing packages that are absent:

sudo apt-get install qtmultimedia5-dev libqt5multimediawidgets5 libqt5multimedia5-plugins libqt5multimedia5

and restart your Qt Creator after that. Cheers.

UPDATE. If it will not work, try another solution:

sudo apt-get update
sudo apt-get build-dep qtmultimedia5-dev
sudo apt-get source --compile qtmultimedia5-dev

UPDATE 2 For me the solution was the following:

  1. Download sources from http://download.qt.io/development_releases/qt/5.4/5.4.0-rc/submodules/

  2. Build them, add the library manually.
