cmake: don't use find_package(Eigen) if we already have the target #2

When using QGP3D inside algohex, an Eigen target is already created, we don't want to find it again (and possibly mix and match eigen versions). Noticed as the container I'm building in doesn't have a globally installed Eigen.

Sorry for taking so long, this has now finally been fixed.
