I've just tested this, but it gives me a python stacktrace if I run it without
passing a --ninja argument to configure. With a bit of extra debugging added to see
what is being generated:
###XXX ['C:/msys64/mingw64/bin/ninja', '--version']

It seems that it doesn't like parsing the discovered ninja path. I can make configure
work by passing --ninja=ninja to configure which falls back to PATH and appears to do
the right thing:
###XXX ['ninja', '--version']
Found ninja.EXE-1.10.1 at C:\msys64\mingw64\bin/ninja.EXE
I tried a few other things too:
--ninja=C:/msys64/mingw64/bin/ninja - fails
--ninja=C:/msys64/mingw64/bin/ninja.exe - works
--ninja=ninja.exe - works
--ninja=/c/msys64/mingw64/bin/ninja - fails similar as above
--ninja=/c/msys64/mingw64/bin/ninja.exe - works
--ninja=C:\\msys64\\mingw64\\bin\\ninja - fails similar as above
--ninja=C:\\msys64\\mingw64\\bin\\ninja.exe - works
>From these tests it looks as if the .exe prefix is required when using a full path to
the ninja executable.
ATB,
