Hi,
I am getting the below error while building source code from the Ubuntu Terminal.
/usr/bin/ld: cannot find -lQt5Quick
/usr/bin/ld: cannot find -lQt5Qml
/usr/bin/ld: cannot find -lQt5XmlPatterns

Any pointers will be helpful. Thank you.

@AkshayChoudhari
try remove -l when you try to find the library on your system

Qt5Qml

.so file are present on below location: "/opt/Qt5.6.3/5.6.3/gcc_64/lib".
But don't know why it is not found at compile time.

Add in your PRO file
QT *= quickwidgets qml quick

Check, maybe not all keys are needed for you

QT *= quickwidgets qml quick

QT += quickwidgets qml quick

@jsulm
Should give the same result.

Please, See operators paragraph.

I think I can do the same thing with QT

@CP71 Yes, you're right. Never used *= so far :-)
