Link with QT creator

I have just installed gstreamer version 1.24.0 on my windows 10 and set the environmental variables.I tested the gstreamer commands like videotestsrc,udp streaming, video audi muxing, saving the file.etc., But,I’m unable to include the gstreamer library into the .pro file in Qt creator. I’m using Qt version 5.15.2 and my compiler is MINGW compiler.
