Commit ef3c5e5516 changed the way
WEST_TOPDIR is initialized from calling 'west topdir' as a subprocess
to using the west API.
However, WEST_TOPDIR is a cmake variable and must be a cmake-style
path, with forward slashes. While 'west topdir' as a command does
output a forward slash separated path (basically in order to make the
zephyr build system work), west_topdir() as an API returns the path in
the host environment path style, which on Windows uses backslashes.
This turns out to be the ultimate cause of the following build error:
CMake Error at C:/.../CheckCCompilerFlag.cmake:41 (set):
Syntax error in cmake code when parsing string
-fmacro-prefix-map=C:\Users\Marti\zp=WEST_TOPDIR
Fix it by converting to POSIX style in Python. We could have
potentially also done this using file(TO_CMAKE_PATH "${WEST_TOPDIR}"
...), but I'm intentionally repeating the old way of doing things
since it was known to work.
