zlib.lib exists in zlib123-dll\lib, and zlib.h in zlib123-dll\include.I have tried various extra_inc_path variations, but I'm not able to get it to work.
Which zlib are you using? It is stated clearly in INSTALL.scons that you need official zlib package (not the mingw one). scons looks for zdll.lib, not zlib.lib. Cheers, Bo
