make error

[npcdna]

when i use 39b5a8a1 to make, i meet 3 problem; First cmake error! In tests/CMakeLists.txt: cmake_policy(SET CMP0104 OLD) and then, i solve this problem by change this line to: if(POLICY CMP0104) cmake_policy(SET CMP0104 OLD) endif() second cmake success, but make error: fatal error: sophus/se3.hpp: No such file or directory 18 | # include "sophus/se3.hpp" then I solve this line by change the code in SophusSelector.h: // #ifdef SAIGA_SYSTEM_SOPHUS // # include "sophus/se3.hpp" // # include "sophus/sim3.hpp" // #else #include "External/se3.hpp" #include "External/sim3.hpp" // #endif third i met error: Snake-SLAM/External/saiga/src/saiga/vision/imu/DecoupledImuSolver.cpp:117:12: error: ‘using PGOSolver = struct Eigen::Recursive::MixedSymmetricRecursiveSolver<Eigen::SparseMatrix<Eigen::Recursive::MatrixScalar<Eigen::Matrix<double, 9, 9> >, 1>, Eigen::Matrix<Eigen::Recursive::MatrixScalar<Eigen::Matrix<double, 9, 1, 0, 9, 1> >, -1, 1> >’ {aka ‘struct Eigen::Recursive::MixedSymmetricRecursiveSolver<Eigen::SparseMatrix<Eigen::Recursive::MatrixScalar<Eigen::Matrix<double, 9, 9> >, 1>, Eigen::Matrix<Eigen::Recursive::MatrixScalar<Eigen::Matrix<double, 9, 1, 0, 9, 1> >, -1, 1> >’} has no member named ‘Init’ 117 | solver.Init(); | ^~~~

but i don't know how to solve this problem
