bug#47561: MIA 2.4.6 fails to build

[Ludovic Courtès]

MIA 2.4.6 fails to build as of 9098745b181b3022587a35afd255f7ff1d41ac86
presumably due to CMake shenanigans as reported here:

  https://issues.guix.gnu.org/46724#9

Build failure looks like this:

The problem here is what we’re missing -I flags for VTK, which might be
a CMake incompatibility issue.

Thoughts?
