[gtk-osx-users] gtksourceview-4.8.1: ERROR: Dependency "vapigen" not found

[Pascal <p p14 orange fr>]

Hello,

I've got this error:
% jhbuild build gtksourceview3
...
*** Configuring gtksourceview3 *** [28/28]
...
Run-time dependency vapigen found: NO (tried pkgconfig, framework and cmake)
../../../../gtksourceview-4.8.1/meson.build:105:2: ERROR: Dependency "vapigen" not found, tried pkgconfig, 
framework and cmake

How to add vapigen to gtksourceview dependencies?

Thanks, Pascal.
