I'm trying to get involved in open source and also am quite interested in robotics, so I thought about contributing to MoveIt 2. As a first step, I'm installing MoveIt 2 from source on my Ubuntu 20.04 VM in VirtualBox.
I've run through all the instructions here: https://moveit.ros.org/install-moveit2/source/#:~:text=colcon%20build%20%2D%2Devent%2Dhandlers%20desktop_notification%2D%20status%2D%20%2D%2Dcmake%2Dargs%20%2DDCMAKE_BUILD_TYPE%3DRelease
However, the build is failing on the highlighted part. The error message is as follows:
Starting >>> geometric_shapes
--- stderr: geometric_shapes
CMake Error at CMakeLists.txt:47 (find_package):
By not providing "Findeigen3_cmake_module.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"eigen3_cmake_module", but CMake did not find one.
Could not find a package configuration file provided by
"eigen3_cmake_module" with any of the following names:
eigen3_cmake_moduleConfig.cmake
eigen3_cmake_module-config.cmake
Add the installation prefix of "eigen3_cmake_module" to CMAKE_PREFIX_PATH
or set "eigen3_cmake_module_DIR" to a directory containing one of the above
files. If "eigen3_cmake_module" provides a separate development package or
SDK, be sure it has been installed.

Any help is really appreciated. Thanks!
You have to install ROS2 before building Move It 2. After installing the ROS2 binaries, the error doesn't occur.
