Yeah, and currently the plugins each check for the same shared
dependencies, but it doesn't show what they're checking for, it just
shows the plugin's name, like:
checking for DEVHELP ... no
What I'm asking about is to have a webkit.m4 (for example) or something
that the plugins which use that dependency can make use of and so the
check is only done once and if not found, it ouputs as I said
previously. Of course I don't know if it's realistic/feasible, which is
why I was asking.

I mean they should require the same version, the same *lowest* version
they can work with (even if they need some minor changes to make it

Not what I meant. But it's sort of what we do now if you consider
building geany-plugins as a whole.

What I was asking about wouldn't be a hack, it would just be to change
the plugins a bit so they depend on the same version of shared
libraries, and then to have Autotools do a check for the shared dependency.
For a list of the dependencies, you can look through the `build`
directory's .m4 files and manually extract them (like I did for some of
the shared ones previously). The ones with the highest versions will be
the "minimum version required" to build geany-plugins (as a whole).
