/usr/bin/ld: cannot find -lEigen3::Eigen about pymagsac

[Smellly]

Update my Eigen version from 3.2 to 3.3.9 (git clone && make && make install)
Then replace find_package(Eigen3 REQUIRED) to
list(APPEND CMAKE_INCLUDE_PATH "/usr/local/include")
find_package (Eigen3 3.3 REQUIRED NO_MODULE)

it works for me.

Sorry, cannot help you here. Eigen linking might be tricky, but I cannot do remote debugging.

I spent ~2-3 hours on this problem before finding this comment and it is solved!

Note to others: My include path was different. If somebody reads this commend and the solution does not work, be careful with your includes path!
