Hi,
According to bug#47463[^1], Blender is missing a dependency that
doesn't allow to run the Voxel Remesher.
This series of patches solve that.
I have a comment on the first one. I'm not sure if I did it right.
I don't see a better way to set the `rpath` correcty. It should
find the lib by itself but the package has an executable as
ouput that doesn't find the library the package itself generates.
Removing the extra phase I added shows the RPATH is set to `lib`
instead to the absolute path of the library so the runpath check
fails to execute.
This is the best way I found to solve that but I'm sure whoever
that gets this patch knows a better way to handle that.
I tested Blender with this and it runs the Voxel Remesher as
expected.
Please, don't hesitate to send me any comment.
Thanks!
