2019-05-11 10:29:27 -0500 | marked best answer | CMake Error: The following variables are used in this project but they are set to NOTFOUND. Hello everyone, Actually, I am working on Ubuntu 14 and Indigo Version, so am trying to make some packages. I got an error message below : I tried to use ROS_LANG_DISABLE like is mentioned in ROS EnvironmentVariables : $export ROS_LANG_DISABLE=genlisp but this can not solve the problem. How would I fix it? Thanks. Edit: Thanks for your help @gvdhoorn, and I'm going through the tutorial modbus to install it, and there is my CMAKE File below : It seems that my environment is set correctly! But I don’t know where is the problem and how can I resolve it??! |
