Using Eigen (Third Party Library) in my plugin

Hey everyone,

I am working on a plugin and wish to use the included third party library Eigen (Engine->ThirdParty->Eigen) to handle the matrices. Fortunately I can see that there are a handful of other plugins that use Eigen (FullbodyIK, AlembicImporter etc) and the way in which they include the library is to include the module “Eigen” in the build file and then encase “#include <Eigen/Dense>” in some code to emit errors when Eigen is needed. When I do this myself though I have no such luck. It simply says it can’t find the library.

Does anyone have any ideas as to why this wouldn’t work? I feel I am missing a step when including Engine->ThirdParty libraries :confused:
