Header only format causing indexing problems with XCode

[Bambofy]

Describe the issue

Hi when XCode tries to index it gets stuck at the tinygltf header file because it contains all the code. Is there a way to have the implementation and definitions seperated so that it doesn't have to parse the implementation when it needs to index?

To Reproduce

• OS: Mac OS X
• Compiler: Clang

Expected behaviour

Indexing should complete normally like other libraries.

There may be a macro to controlling indexing in XCode as done for IntelliSense

tinygltf/tiny_gltf.h

Line 1493 in 16c2d3a

#if defined(TINYGLTF_IMPLEMENTATION) || defined(__INTELLISENSE__)

Contribution of XCode version of way for controlling indexing is much appreciated!
