Bullet stack
i want to use some elements of bullet library in my code.
In particular I want to convert from quaternions to roll,pitch and yaw.
I've seen that i can do:
btQuaternion q;
double roll, pitch, yaw;
tf::quaternionMsgToTF(msg->pose.pose.orientation, q);
btMatrix3x3(q).getRPY(roll, pitch, yaw);
But I don't know how to include the bullet library in my code. Any help?
