Cannot start a new gtkmm project
When starting a new gtkmm project, I get a message that gtkmm-3.0 is missing. However, pkg-config --modversion gtkmm-3.0 reports: 3.24.2
As I'm using slackware, all .h (and, as shown above) the .pc files are also present.
Why do I get this issue?
Edit Just tried to create a simple new C project, and I get that gtk+-3.0 isn't available either. I've been working on an existing gtk3 project for the last weeks without any problem.
