What version of fvwm are you trying to build?  The current unstable version
(2.4.15-2) does not seem to have a (direct or indirect) build-dependency on
libpng-dev, so I cannot reproduce this at all.

pn  libpng-dev     <none>         (no description available)
pn  libpng10-dev   <none>         (no description available)
pn  libpng12-0-dev <none>         (no description available)
pn  libpng12-dev   <none>         (no description available)
pn  libpng2-dev    <none>         (no description available)
pn  libpng3-dev    <none>         (no description available)
