ftlib.h wasn't found in -I../../lib -I../../lib/.. or any other default -I

typically, include files are installed in /usr/include /usr/local/include
/opt/include or /usr/local/include/<packagename>

you'll need to find where flow-tools installed them (or, if you didn't
install them, do so) and try again.

since you don't say how you installed flow-tools, best this list can do
is guess as to where they are.

i'm not sure what kind of build environment you're trying to pull off,
but it isn't working.

fix the include path and the rest should work itself out.
