dolfin doesn't find the pybind11 module during the build, however it has
a build-dependency on that.  So I assume that it is meant to do
something senseful with that build-dependency.

The build still succeeds, so maybe add a check that some artifacts added
with that component show up in the packages?

   The OLD behavior for policy CMP0148 will be removed from a future version
   of CMake.

   The cmake-policies(7) manual explains that the OLD behaviors of all
   policies are deprecated and that a policy should be set to OLD only under
   specific short-term circumstances.  Projects should be ported to the NEW
   behavior and not rely on setting a policy to OLD.
