Gstreamer not detected when building

[dynamodan]

I get an error when building on ubuntu 18.04:

pipeviz$ qmake pipeviz.pro
Project ERROR: Package gstreamer-1.0 not found

I have gstreamer installed so I don't know what else to do:

pipeviz$ gst-launch-1.0 --version
gst-launch-1.0 version 1.14.5
GStreamer 1.14.5

Thanks in advance for your help.
