I installed the vte-0.28.2p19 package and that problem was solved. New problem is that the built fails with an undefined reference error:

[config.log](https://github.com/geany/geany-plugins/files/2789099/config.log)
Could be related to @LarsGit223 's comment, as I see that function seems to be defined in the utility library.
I tried preceding the configure command with PTY_LIBS="-lutil" and LDADD"-lutil" but no effect.
