make error

Hi, @mbrossar I tried to compile libpointmatcher but it reported some errors. /usr/bin/ld: ../libpointmatcher.so.1.3.1: undefined reference to Nabo::NearestNeighbourSearch<double, Eigen::Matrix<double, -1, -1, 0, -1, -1> >::create(Eigen::Matrix<double, -1, -1, 0, -1, -1> const&, int, Nabo::NearestNeighbourSearch<double, Eigen::Matrix<double, -1, -1, 0, -1, -1> >::SearchType, unsigned int, Nabo::Parameters const&) However, I also tried to compile the original libpointmatcher and only succeed with the master branch libpointmatcher issue. I installed libnabo 1.0.7 successfully. Do you have any ideas? Thanks.
