Disclaimer: I have posted the same issue over at https://github.com/cocos2d/cocos2d-x-samples/issues. I realise that cross-posting is usually not encouraged. However, after having a closer look at mentioned issues page on posted GitHub page, it seems to me that that page is highly inactive, and posting here has a far higher chance of valid and useful input.
I've been trying to build the cocos2d-x samples by following the steps from https://github.com/cocos2d/cocos2d-x-samples exactly, namely
Download
$ git clone https://github.com/cocos2d/cocos2d-x-samples.git
$ cd cocos2d-x-samples $ python download-engine.py
Running
Once the samples were downloaded just go any sample, and open the project. eg:
$ cd cocos2d-x-samples/samples/LiquidFun-Testbed/proj.ios_mac
$ open LiquidFun-Testbed.xcodeproj/
However, when I build the LiquidFun-Testbed.xcodeproj, while targeting iOS, I get
Showing All Errors Only
Prepare build

It looks like the compiler is looking for files in
/Users/Chris/Desktop/source/repos/3rd party libraries/cocos2d-x-samples/libs/liquidfun/liquidfun/liquidfun/Box2D/Box2D/
but this path was never created.
After following the mentioned steps above, Box2D and its code are instead placed in
/Users/Chris/Desktop/source/repos/3rd party libraries/cocos2d-x-samples/libs/cocos2d-x/external/Box2D
...So I am wondering
A) Why is it looking for these files in
/Users/Chris/Desktop/source/repos/3rd party libraries/cocos2d-x-samples/libs/liquidfun/liquidfun/liquidfun/Box2D/Box2D/?
B) What can I do to fix this and get these samples to build?
