Sample crash on iOS devices

[artgolf1000]

Hi,

I had reported the issue to Github, when I enable sound, the app will crash on iOS devices every time.

I guess that the issue was introduced recently, for it does not exist before I pulled the latest master branch.

How to repeat the issue:

Modify any of the samples codes, enable sound in the engine, build and run, the app will crash.

It reports that 'AudioQueue EXC_BAD_ACCESS', I can not figure it out.

I have tried to check out an earlier version to test if it is a bug.

cd Urho3D
git checkout f1cb469a34c13c56e9d6a9a75c38539cf2de8bd2 .

This version was committed on Nov 9, 2016, it can work without any issues, so it is a bug.

Could you do git bisect until you find the first commit that caused your issue?

Hi,

I traced the commit log, and found the commission:

Another attempt to auto-detect clock_gettime() on Apple platforms.
It is strange that Apple does not honour the deployment target and only based on base SDK when defining __CLOCK_AVAILABILITY internally.

I rolled back to the previous version (Source/ThirdParty/Civetweb/CMakeLists.txt), the issue disappears.

Either way is not bulletproof, I am afraid.
