Hi Alexey!
I had a look at the newly added contrib section you posted in comment #12,
here is a short summary of my "investigations":

As remarked in 

https://bugzilla.redhat.com/show_bug.cgi?id=753577#c13

this appears to be non-free. I could build the gmsh rpm with 
-DCMAKE_ENABLE_BLOSSOM:BOOL="OFF".

We should probably ask upstream :)

License is GPLv2+ according to

This is licensed under GPLv3 according to

LGPLv2 according to

http://math.lbl.gov/voro++/download/

Modified BSD (http://math.lbl.gov/voro++/download/). The license text  is also
part of the gmsh/contrib/voro++ source. 

The voro++ source in gmsh is pristine voro++ 0.4.4 plus one tiny bug fix
according to a diff I did. Newest upstream  of voro++ is 0.4.5 including this
patch.

So some possible actions
- remove blossom
- clarify HighOrderMeshOptimizer is part of gmsh
- check whether lbfgs, Salome and mmg3d are modified and if not 
  what to do about it (bundling vs. packaging) since the sources are not  
  available as packages in fedora(AFAIK). 

What do you think? Are there any more actions need to be taken?
I will write upstream and ask about these contrib sources in gmsh. 

Cheers,
Andre
