Adding custom target in qmake

Question

I want to build my resources with qmake as follows [Qt 5.5]:

imageTarget.target = images.rcc
imageTarget.depends = $$PWD/images.qrc
imageTarget.commands = r         


        

Answer 1

With

QMAKE_EXTRA_TARGETS += imageTarget

you just define a new target - but it is not automatically built when running make.

Try to add

PRE_TARGETDEPS += images.rcc

This should automatically build a new images.rcc when running make if images.qrc has changed.
