How to reduce build time in QT

Apoorvthedude

Hi,I m new to qt qml and i have assigned some task in which I have to change some ui in QgroundControl.

I have only installed dekstop gcc and qt charts as per my requirement very less dependencies.

But each time i change some little piece of code,it takes very much time to build.
(My pc is also slow
Specs:4gb ram
i3,OS:Linux kernel)

Please help or suggest some ways to reduce build time.

it takes very much time to build

How much?
How big is the code base?
How exactly do you build (in QtCreator, in a terminal)?
Does it rebuild everything if you change one file?
