Hi, I've installed ROS2 Foxy on Windows 10. Able to run talker and turtlesim examples without issues.

I'm going through the 'Creating a workspace' tutorial and colcon build --merge-install gives me the following error:

Windows10 ROS2 Foxy 'colcon' is not recognized as an internal or external command, operable program or batch file.

I've already done this to my workspace: call "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" x86_amd64

Colcon has already been installed using the following: python -m pip install -U colcon-common-extensions
