SciberQuestToolkit plugin: provide a way to use system eigen libraries
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Would it be possible to provide a way to make use of eigen libraries already installed in a system rather than having paraview bundle an old version of the same? A CMake variable that allows something like DUSE_SYSTEM_EIGEN would be much appreciated. The benefits would be reduced size of the installation, but more importantly maintaining coherence with upstream versions making it easier to hunt and fix possible issues.
In case that is not possible, kindly consider updating the bundled eigen libs to the current upstream stable (3.1.1). The issue first arose from the eigen 3.0.3 being licensed as GPL-2.0+ / LGPL-3.0 while paraview itself is BSD-3 and the two licenses conflict . Eigen has since been relicensed as MIT, and that should fix any apparent conflict, as MIT is a permissive license similar to BSD-3.
