some troubles on installing deja-dup from source code

*(Learning how to install programs on linux...)* deja-dup source code can be downloaded on its GitHub repo. There is a makefile con the package. Once into the folder I run: santi@eoan:~/deja-dup$ make And get the error: The Meson build system Project name: deja-dup Project version: 40.6 ... Run-time dependency goa-1.0 found: NO (tried pkgconfig and cmake) Run-time dependency json-glib-1.0 found: NO (tried pkgconfig and cmake) meson.build:36:0: ERROR: Dependency "json-glib-1.0" not found, tried pkgconfig and cmake A full log can be found at /home/santi/deja-dup/builddir/meson-logs/meson-log.txt make: *** [Makefile:15: configure] Error 1 I'm running lubuntu eoan, where deja-dup is updated, or almost. I wanted to know what's going wrong for future reference though.
