export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/non-standard-place/libpng-dir/lib/pkgconfig/
and then run your configure.
You may have to do this for other packages as well.

Hello,
I am newbie so please excuse me if i am asking childish thing. So now
the point is i have already working GTK of version 1.2 something. So
now i tried to upgrade it by installing gtk 2.20.0. So i followed
needed procedures.
Installed latest pkg-config, lib png 1.4.x, freetype, fontconfig,
glib, pango atk,
laterward tried cairo 1.8.8, while configuring i faced following problem
/opt/newgtk/ is my directory for new gtk tried to keep separate from
older version
linux:/opt/newgtk/cairo-1.8.8 # ./configure --prefix=/opt/newgtk/
.
.
.
.
.
.
.
checking for cairo's PNG functions feature...
configure: WARNING: Could not find libpng in the pkg-config search path
checking whether cairo's PNG functions feature could be enabled... no
configure: error: recommended PNG functions feature could not be enabled
But i have already installed linpng then also why i am facing this problem dono
i have libpng 1.4.X but my cairo is 1.8.8 Is there any version
incompatibility is there between these?
So can a kind soul tell me what my problem is?
Thanks & Regards,
Guruprasad.
