Maxime, All,

The comment "# libpthread-stubs" seems to imply that the dependency on
C++ is ihnerited from libpthread-stubs, but it is neither selected not
depended on; it is also not in the build dependency. Is it an oversight?

However, given the name of the package, I guess it needs C++ for itself.
So, whether libpthread-stubs is needed or not, you should drop the
comment altogether: C++ *is* needed by kms++.

Drop the comment about the Python bindings, since we don't support them
(you dropped them sinc e v2 of the patch).

Usually, when there is a single option to a package, we do not use an
if-block, but just make that option depend on the package. But I'm fine
with an if-block (I prefer it; it's just not what we usually do).

No empty line above.

Since it installs libraries, maybe it should be installed in staging as
well?
