CMake fails with Eigen 5.0. #5724
Description
CMake fails with Eigen 5.0.
FindEigen3.cmake relies on Eigen version, but the versioning system changed with Eigen 5.0. See:
This release marks a transition to Semantic Versioning. Previously, Eigen used a WORLD.MAJOR.MINOR scheme. From now on, version numbers will follow the MAJOR.MINOR.PATCH format, indicating breaking changes, new features, and bug fixes, respectively. The WORLD version will remain 3 for this and subsequent releases for posterity.
