 These environment variables become available after setup-python action execution:
 
-| **Env.variable**      | **Description** |
-| ----------- | ----------- |
-| pythonLocation      |Contains the absolute path to the folder where the requested version of Python or PyPy is installed|
-| Python_ROOT_DIR   | https://cmake.org/cmake/help/latest/module/FindPython.html#module:FindPython        |
