[vtkusers] Migration to VTK6

[David Gobbi]

Hi Arno,

You can try replacing FindOpenGL.cmake with the latest one from the cmake
master branch:
https://cmake.org/gitweb?p=cmake.git;a=blob_plain;f=Modules/FindOpenGL.cmake
On my machine, for example, the file is located here:
/Applications/CMake.app/Contents/share/cmake-3.4/Modules/FindOpenGL.cmake
That might help with AGL.

 - David
