[Stk] Using the STK with Xcode 4

[Ariel Elkin]

I've been using the MoMu release of the STK without problems on projects built with Xcode 3, but I'm now getting build problems on projects built with Xcode 4.

I drop the library into the Xcode 4 project and it builds fine, but as soon as I #include it, I get a "Lexical or Preprocessor Issue" error, more specifically " 'string' file not found, on line 4 of Stk.h.

On closer inspection, the error specifies that 'string' file not found in ~/my project's/directory/include/mainheader.h

So it thinks that header file is in my project directory, but it's obviously a C/C++ header… How can I tell Xcode to look for these C/C++ headers?

I've tried the solutions listed here: http://stackoverflow.com/questions/5584317/compile-build-or-archive-problems-with-xcode-4-and-dependancies
but none worked.

Here's a simple project that illustrates the error:

Any suggestions?
