[ATLASUI] Build atlasUI inside xcode missing libpng, libjpeg

[trompetin17]

I downloaded the svn project, use cleanworkspace.sh and then updateworkspace.sh, open Xcode, change the schema to add "AtlasUI" in the target(see the image attached) and add the flag "-editor", finally press build and I'm getting an error about missing libpng

    Ld /Users/juanguillermo/Documents/0ad/binaries/system/libAtlasUI_dbg.dylib normal x86_64 (in target: AtlasUI)

I have to manually add libpng in AtlasUI->BuildSettings in Header search paths : ../../../libraries/osx/libpng/include Library search paths: ../../../libraries/osx/libpng/lib

and when I rebuild once again now Im getting the error

that in this case I only add in AtlasUI->BuildSettings in Header search paths : /usr/local/include Library search paths: /usr/local/lib

and now all build correctly.

But why this happened?

Looking inside premade5.lua I found that libpng is missing in atlas_extern_libs(line 1139), so I added and repeat the steps and now no error about missing libpng.

Anyone who knows what else could be the problem
