Building px4 with new mavlink v2.0 error

I beganto build from windows make firmware but notice at the end of build that there are 2 days ago mavlink v2.0 I downloaded and repaced with v1.0 but have error

#include "include/mavlink/v2.0/ardupilotmega/mavlink.h"
I also added C:\Users\user\Documents\GitHub\ardupilot\modules\PX4Firmware\mavlink\include\mavlink\v2.0\ardupilotmega
and here becouse not sure C:\Users\user\Documents\GitHub\ardupilot\modules\mavlink\include\mavlink\v2.0
but get error that no such file or directory “include/mavlink/v2.0/ardupilotmega/mavlink.h”

Thank you for your advice

I have got the same error message on linux build. You need to add 2 Python packages: “lxml” and “future”.

Open this web page: http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml
search and download, "lxml-3.6.4-cp27-cp27m-win32.whl"
search and download, “future-0.15.2-py2-none-any.whl”

These can be installed by running:
pip install filename
