go-task pkgconfig -- gtk+-3.0
task: [pkgconfig] /home/thomas/Projects/SolusPackaging/common/Scripts/epcsearch.py gtk+-3.0
pkgconfig(gtk+-3.0) found in: libgtk-3-devel
So that dependency is the libgtk-3-devel
package
Easy to find with the go-task
commands and/or epcsearch.py
script from the packages
repository as used in the above example. Unfortunately a bit overkill to install them if you're not packaging for Solus.
