As discussed in #20, the licence of original gmapping source has been changed to BSD, and all contributors on this repository agreed changing their code into BSD except @vrabaud , so I first fork original gmapping source tree as melodic-branch (79ef0b0e6d9a12d6390ae64c4c00d37d776abefb) and changed from rosmake to catkin (this is main contribution of @vrabaud )and add missing patches
