cmake not working, could not exec qmake
For newer versions of Ubuntu, if you have only installed version 5 of the Qt Framework, you may get this error. If you want to use Qt version 5 by default, then you should run the following command to fix the error:
sudo apt install qt5-default
You need the qt
dependences:
sudo apt-get install qt4-qmake libqt4-dev
Does the trick:
sudo apt-get install qt4-qmake
You do not need to install half a gigabyte of qt sdk!
I read on another post that the problem has something to do with CMake not being able to find Qt4 qmake.
However in my case, it was simply a matter of not having qt4-qmake. This solved it (but weighs a heavy 440MB):
sudo apt-get install qt-sdk
