[bug#40492] [PATCH] gnu: Add meshlab

[Ekaitz Zarraga]

Hi everyone,

I wrote a package to add meshlab but I'm not sure if I did it right:
- It doesn't have tests so I removed the testing.
- It fails to check RUNPATH, but I don't really know why so I disabled
  it at the moment. It fails while searching for meshlab core libraries
  but the search path is correct (it misses a /meshlab at the end).

Can you please check it and suggest a solution?

It works as it is but the runpath checks should pass...

Thanks!
Ekaitz
