[Mesa-users] [mesa-users] Configuring mesa-11.2.2 llvmpipe with non-standard paths

[Chuck Atkins]

If you want to try the el6 and el7 binaries generated from the docker
images, they're available here:

https://data.kitware.com/#user/56eac32b8d777f0457177859/folder/56eac32b8d777f045717785a

If you have further issues related to configuring mesa specifically for VTK
or have any run-time issues when using it then we should probably move the
discussion over to the vtk-users mailing list.
