Cannot build with python nor MESON

Windows 7 64-bit
Tested on Python 2.6 32-bit and 64-bit same error output

C:\jsoncpp-master>python amalgamate.py
Amalgamating header...
Traceback (most recent call last):

    f = open(os.path.join(self.top_dir, relative_input_path), "rt")
IOError: [Errno 2] No such file or directory: 'C:\\jsoncpp-master\\include/json/

I just followed these steps: Amalgamated source but it's not working for me, why?

EDIT:
I tried with MESON, but it didn't help:

Looks like your meson isn't working because you don't have a compiler installed.

I have a fix for the amalgamate script, this has been an evolving issue recently. I will close this issue when that PR is checked in, thanks!

Thank you, your fix worked for me, I built that by the amalgamate script, it should be merged in the master branch which is really a mess.
