Subproject X did not override X dependency and no variable name specified

[kraftwerk28]

I'm trying to build https://gitlab.gnome.org/raggesilver/blackbox, using the following subprojects/marble.wrap file:

[wrap-git]
url = https://gitlab.com/raggesilver/marble.git
revision = master

But running meson setup --buildtype=release build outputs:

WARNING: Subproject 'marble' did not override 'marble' dependency and no variable name specified
Dependency marble from subproject subprojects/marble found: NO

How this can be solved? Thank you in advance.

marble declares a variable marble_lib_dep, and Meson is suggesting that you should specify that as documented in https://mesonbuild.com/Wrap-dependency-system-manual.html#provide-section
