EIGEN_PI error
Description of issue
I got this error (on ubuntu 19.10, compiling from git): /usr/include/osvr/Util/EigenQuatExponentialMap.h:164:31: error: ‘EIGEN_PI’ was not declared in this scope;
temporary SOLUTION : add the following line on top of /usr/include/osvr/Util/EigenQuatExponentialMap.h after the line including EigenCoreGeometry.h : #define EIGEN_PI 3.141592654
hint: before compiling from git clone, maybe try : git submodule update --init --recursive
