Hi,

On running:

west build -b native_posix samples/hello_world

I get the following error, any advice or suggestions ?

-- west build: build configuration:

       source directory: /media/andrewh/SOURCE/Source/zephyrproject/zephyr/samples/hello_world

       build directory: /media/andrewh/SOURCE/Source/zephyrproject/zephyr/build

       BOARD: native_posix (origin: command line)

-- west build: generating a build system

CMake Error: The source directory "" does not exist.

Specify --help for usage, or press the help button on the CMake GUI.
