proposed Portfile for vtk 8.2.0

[snarkhunter (Steve Langer)]

vtk 8.2.0 fixes bugs that I care about in 8.1.2, so please do upgrade.

I tried building 8.2.0. with the Portfile from 8.1.2, but had to make some modifications to get it to work. I've attached the modified file, which works for me, but I don't really know if the changes that I made are correct. I just added dependencies and config arguments until the compiler stopped complaining.

Thanks. ​Per the guidelines, please instead attach a unified diff of the Portfile so we can easily see what changes you are proposing. Or better yet, submit a pull request.

diff that upgrades Portfile for vtk 8.2.0

[snarkhunter (Steve Langer)]

I added the diff. I hope I did it correctly.

I believe that the existing patch in files/patch-python37.diff needs to be updated, but since I'm not using any of the pythonxx variants of vtk I have no way of testing it, and didn't try fixing it.

Thank you. A few comments:

• You have added eigen3 as a dependency, can eigen3-devel also work? If so, you need to use a path reference. Like this:

path:include/eigen3/Eigen/Eigen:eigen3

• Please sort all of the depenencies.

eigen3-devel appears to work. I don't know how to run the vtk test suite on the macports build, but it compiles without error and I run my vtk-based application.
