ros2 branches cannot be built on windows10

[wangruoyao]

I tried to build it in win10 but failed.
I'm using ros2-foxy.

C:\dev\ros2_foxy\vision_opencv-ros2>git checkout ros2
fatal: not a git repository (or any of the parent directories): .git

C:\dev\ros2_foxy\vision_opencv-ros2>colcon build --symlink-install

Could not find a package configuration file provided by "ament_cmake_ros"

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

after amend CMakelist and install boost. I build the image_geometry successfully but still cannot build cv_bridge without any information.
