Sorry, I should have said that I was working on it.

Maybe you can have a look. I solved some parts differently, but I copied your
approach towards Leap. (With a minor adjustment: copy_options is already
available with Boost 1.75.)

Yes, unfortunately we had to patch out some stuff.

Upstream seems to target Boost 1.83 for now, the relevant change is only in
Boost 1.85.

I don't use RStudio a lot, but most of the stuff I've been doing in the past
continues to work.

Interestingly, SLE has Boost 1.75 since SP3
(https://build.opensuse.org/package/show/SUSE:SLE-15-SP3:GA/boost.175), but
instead of libboost_*-devel it provides libboost_*-devel-impl. And it conflicts
with Boost 1.66, which we transitively require via e.g. soci-devel.

So I think patching it as you did is our only option.

I think we shouldn't do

BuildRequires:  openSUSE-release

Because it might cause frequent rebuilds (at least in the devel project) and it
doesn't sound right. RStudio being a part of the distribution shouldn't depend
on it. I'd propose to just patch this out. There is nothing SUSE-specific at
the moment in the CMake files, and if there is it might not work for Tumbleweed
anyway.
