[Interest] Building Qt from Sources

[1+1=2]

Hi Szalata,

First, you can run “qmake -v” or "which qmake" to find which version
was used when you call the qmake.

If wrong version was called, you can simply using
"/opt/qt/qt-4.8.0/bin/qmake" when you needed qmake.

If you still come with problem, given the ERROR message.

Regards,

Debao
