Dune configurator and MULTIPLES pkg-config libs

Hello folks!
I’m new to dune configurator using pkg-config queries.
I’m wondering how to fetch configuration for multiples libraries using pkg-config, the example https://dune.readthedocs.io/en/latest/quick-start.html#defining-a-library-with-c-stubs-using-pkg-config is showing a single dependency, how do you write such an example for multiple (C) libs you depend on? Also, how do you aggregate cflags and libs before converting them to sexp?


RTFM, Philippe:

query pkg-config for the package. The package must not contain a version constraint. Multiple, unversioned packages are separated with spaces, for example “gtk±3.0 gtksourceview-3.0”. Returns None if package is not available.
