n2: error: parse error: failed to scan ident
CMakeFiles\rules.ninja:3:

The line ending of file CMakeFiles\rules.ninja:3 is CRLF, convert to LF then it's fine.

But these files are generated by CMake, so n2 should be able support CRLF line ending on windows.

Did you see the bit in the readme about crlf support?
