Package json-glib-1.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `json-glib-1.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'json-glib-1.0' found
In file included from libskypeweb.c:19:0:
libskypeweb.h:29:10: fatal error: glib.h: No such file or directory
OS: Ubuntu 18.04 GCC: 7.3
Ok. apt -y install libglib2.0-dev
pkg-config --cflags --libs glib-2.0
I reassemble and the problem remains the same.
How to fix?
