kiss-icp install

[Sefilevy]

we try to build it on ROS2 by running the code:
"git clone https://github.com/PRBonn/kiss-icp
colcon build
source ./install/setup.bash"
we got the following error:
" colcon build
[0.892s] ERROR:colcon:colcon build: Duplicate package names not supported:

• kiss_icp:
  • kiss-icp/ros
  • src/kiss-icp/ros"

if anyone can help us- much appreciated
