error: undefined reference to `pcl::tracking::KLDAdaptiveParticleFilterTracker<pcl::PointXYZRGB, pcl::tracking::ParticleXYZRPY>::insertIntoBins(std::vector<int, std::allocator >, std::vector<std::vector<int, std::allocator >, std::allocator<std::vector<int, std::allocator > > >&)' could you please give some suggestions?

Solution： modify the code in the SLStudio.pro according to the used system as follows:

Operating System dependant linking and including

Linux

unix:!macx { CONFIG += link_pkgconfig

Link VTK (no pkg-config, only cmake files, hence we link manually for now)
