error: ‘enable_if_t’ in namespace ‘std’ does not name a template type #28

Am I simply missing a compiler flag? catkin build output:

It simply requires C++14. But I just realized this repo became out of synch with MRPT master, sorry for that... Please, if you have some free time, try replacing all lines like this one on all nodes to C++14 and open a PR. It should fix it...
