"itm2mem_info.c" includes "info.h" and "json.h", but it seems that there is no such file in /inc

Start with the README build steps and src/itm2mem_info.c, then inspect the inc directory and the include paths shown by make. Determine whether info.h and json.h are missing, misplaced, or omitted from the build; done means a clean make completes without those header errors.

I just try to build this as the Readme said, i.e. install the dependencies -> . /autogen -> ./configure.sh -> make, but problem occurs:
$ make

Is it possible that I missed something?
