Re: Problem using wx headers in XCode

Hi Tim,

I can't help with Xcode specific variables, but wxWidgets needs two 
include paths. One for the headers, and one for setup.h.
If wx.h and other headers are found the headers seem to be included 
correctly.
setup.h is in the lib folder, and you already include 
$(HOME)/lib/wx/include/osx_cocoa-unicode-3.1
This is folder for wxWidgets 3.1. Are you using this version? The latest 
versions on vcpkg are 3.3 and 3.2 stable. Maybe you need to update this 
path to have the correct version?
And I'm not sure about this one, but you might need to include the path 
with setup.h before including the general wx headers.

Greetings,
Maarten
