Have similar errors here. The problem lies in vlib/pkgconfig which doesn't find the .pc files.. in my file located in /usr/lib/i386-linux-gnu/pkgconfig/gtk+-3.0.pc

Unfortunately still not working in 2024 with Ubuntu 22.04.3 using v 0.4.4.

I found out at least to use these headers in webview_linux.c.v to fix the missing graphene_config.h:

#flag linux -I /usr/include/harfbuzz
#flag linux -I /usr/lib/x86_64-linux-gnu/graphene-1.0/include   
#pkgconfig gtk4     
#pkgconfig webkit2gtk-4.0
#include <gtk/gtk.h>
#include <webkit2/webkit2.h>

Is gtk4 actually supported by webkit2gtk? As far as i see via pkg-config, it is just supporting gtk+-3.0. As i am not a C dependency hell expert, somebody with more experience could have a look on that?
