Problem building libpq

Hi,
I recently updated my compiler going from MSVC 2010 to MSVC 2017.
Now I'm trying to re-build the libpq with it.

[code]
NMAKE : fatal error U1064: MAKEFILE not found and no target specified
Stop.

C:\Program Files (x86)\Microsoft Visual Studio\2017\Community>cd c:\Users\Igor

c:\Users\Igor>nmake

        cd include
NMAKE : fatal error U1077: 'cd' : return code '0x1'
Stop.
[/code]

What am I missing?

Thank you.
