Hi
They want you to type the full path for qmake inside the Qt 5.15.0 folder
so first step is to use the search tool to find out where it is and then use the full path to it
for the compiling.

Might be
/usr/local/opt/qt5
but it depends on where you actually installed it.

That is not using the full path to the qmake executable, that is /qmake which does not exist. If you are a developer you need to understand about paths.

@SGaist wants you to use the full path to your qmake executable (nothing to do with MySQL) when you run your make command, like:

<path-to-qmake-in-your-Qt-distribution>/qmake -- MYSQL_PREFIX=/usr/local/mysql

He wants you to do that to make you run the exact right version of qmake which is in the Qt 5.15 installation area. At the moment there is no qmake on your PATH.
