CMake Error in ROS Navigation
Hi! I followed these steps to install ROS navigation:
cd catkin_ws/src
git clone https://github.com/ros-planning/navigation.git
cd ..
catkin_make
but I have this error
CMake Error at /usr/share/cmake-2.8/Modules/FindPkgConfig.cmake:283 (message):
A required package was not found
Call Stack (most recent call first):
/usr/share/cmake-2.8/Modules/FindPkgConfig.cmake:337 (_pkg_check_modules_internal)
navigation/robot_pose_ekf/CMakeLists.txt:6 (pkg_check_modules)
What does it mean? How do I fix? Thank you!
