Sorry for the slow reply.

How does that work for say distro re-packaging? Note that libcuda.so.1 is a DSO
which ships with the driver, so there's a multi-hundered MB cost to having it
present on a system. I would assume that most distro re-packagers don't install
more graphics drivers than they necessarily need, likely if their focus for a
machine (I think a lot of it is done on VMs these days) is just re-packaging,
it'll just have Mesa as that's default.

Also, I'm a bit confused by the WINE_CHECK_SONAME usage. I skimmed various uses
of it (and the subsequent definitions that it creates) and noticed that it
doesn't pass along information about the SONAME version to the preprocessor.
Maybe I'm misreading something, but it seems like the Wine source has to assume
some given SONAME version of a DSO anyways, it can't tell the difference
between libcurl.so.3 and libcurl.so.4, it will link against whatever it finds
and then hope that the interface it's using matches well enough that it won't
hit issues at runtime.
