Target "badslam_test" links to target "Eigen3::Eigen" but the target was not found. about badslam

I replace find_package(Eigen3 REQUIRED) with find_package(Eigen3 REQUIRED NO_MODULE) and finally it compiles well.

This seems like there must be some error in locating the Eigen3 installation. Badslam's CMakeLists.txt does have a find_package call for it here:

badslam/CMakeLists.txt

Line 72 in 32e47be

find_package(Eigen3 REQUIRED)

Perhaps Eigen3 is installed in a non-standard location on your system? In that case, you could try specifying its path to CMake manually (for example, by checking with ccmake and filling in the Eigen3-related variables that are set to NOT_FOUND)

Hello @lql0602, I got the same problem. Did you solve it?

@neilzhuu Thanks for the update. Eigen also seems to recommend using NO_MODULE (see Using Eigen in CMake Projects), so I committed the change to the repository.
