ROS noetic Build Fails

[JeremiasGaia]

Hi. My openVSLAM installation works fine.
However, recently i tried to install ROS packages following the instructions on https://openvslam-community.readthedocs.io/en/latest/ros_package.html#installation for ROS noetic.

When i run
catkin_make -DUSE_PANGOLIN_VIEWER=ON -DUSE_SOCKET_PUBLISHER=OFF

I get the following error, I hope you can help me

CMake Error at openvslam_ros/CMakeLists.txt:134 (find_package):
By not providing "Findopenvslam.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"openvslam", but CMake did not find one.

Could not find a package configuration file provided by "openvslam" with
any of the following names:

openvslamConfig.cmake
openvslam-config.cmake

Add the installation prefix of "openvslam" to CMAKE_PREFIX_PATH or set
"openvslam_DIR" to a directory containing one of the above files. If
"openvslam" provides a separate development package or SDK, be sure it has
been installed.

Read the error carefully. It means that you have not installed OpenVSLAM.

Ok, by reading your comments I found that in the installation guide the command make install is missing.
If you execute

cd /path/to/openvslam
mkdir build && cd build
cmake \
    -DUSE_PANGOLIN_VIEWER=OFF \
    -DUSE_SOCKET_PUBLISHER=ON \
    -DINSTALL_SOCKET_PUBLISHER=ON \
    -DUSE_STACK_TRACE_LOGGER=ON \
    -DBUILD_TESTS=ON \
    -DBUILD_EXAMPLES=ON \
    ..
make -j4

the code is built, but not installed. Therefore ROS can't find it.
I suggest to add the make install command to the official guide:

cd /path/to/openvslam
mkdir build && cd build
cmake \
    -DUSE_PANGOLIN_VIEWER=OFF \
    -DUSE_SOCKET_PUBLISHER=ON \
    -DINSTALL_SOCKET_PUBLISHER=ON \
    -DUSE_STACK_TRACE_LOGGER=ON \
    -DBUILD_TESTS=ON \
    -DBUILD_EXAMPLES=ON \
    ..
make -j4
make install

thank you for your answer, I hope my feedback helps.
