Problem with Eigen3

I had rename the files of eigen3 to eigen in /usr/local/lib/cmake to compile the opengv.

/usr/local/lib/cmake/eigen3/Eigen3Config.cmake to /usr/local/lib/cmake/eigen3/EigenConfig.cmake
/usr/local/lib/cmake/eigen3/UseEigen3.cmake to
/usr/local/lib/cmake/eigen3/UseEigen.cmake

but have some problems to make the opengv.
/usr/local/include/eigen3/unsupported/Eigen/NonLinearOptimization:15:22: fatal error: Eigen/Core: No such file or directory
#include <Eigen/Core>

Dont have support to Eigen3 ?

I just added a new FindEigen.cmake file in opengv/cmake. It searches for Eigen-headers, and then includes the paths. Note however that my eigen headers are located in usr/include ...

I solved the problem by changing the following:

• find_package(Eigen Required) to find_package(Eigen3 Required) in line 161
• include_directories(${EIGEN_INCLUDE_DIRS} ${EIGEN_INCLUDE_DIR}/unsupported) to include_directories(${EIGEN3_INCLUDE_DIRS} ${EIGEN3_INCLUDE_DIR}/unsupported) in line 162
