Dear maintainer,

these packages

 Assuming you have sourced the ros environment, same below
sudo apt install libgflags-dev  \  
ros-$ROS_DISTRO-image-geometry ros-$ROS_DISTRO-camera-info-manager \
ros-$ROS_DISTRO-image-transport ros-$ROS_DISTRO-image-publisher \  
libgoogle-glog-dev libusb-1.0-0-dev libeigen3-dev

and

git clone https://github.com/libuvc/libuvc.git
cd libuvc
mkdir build && cd build
cmake .. && make -j4
sudo make install
sudo ldconfig # Refreshing the link library

are ALL installable via ROSDEP.
I have included the packages in package.xml and updated the installation instruction in README.md.
