Summary

0015998: Add variable to cmake in order to decide whether building is for android

Description

I'm build a cmake project(YouCompleteMe) under Android. Everything works well except that ld try to link librt wrongly, which has been integrated into Bionic and not available under Android System.

I have googled for a while to look for a solution to detect android system in cmake, but there is none.

If I am building a program for Mac OS X, there is a variable APPLE to tell me that this is a Mac OS X instead of normal BSD. But there is no variable ANDROID to tell me that this is a Android System instead of normal Linux. In my opinion, these two scenes are similar.

Of course, I could define a variable to differ Android from normal Linux. but I guess we need an official way to do this.

Notes
(0040637) Brad King (manager) 2016-03-07 11:25	When cross-compiling to Android one typically uses a toolchain file that sets CMAKE_SYSTEM_NAME to "Android". This value can be tested by project code to check the target system.
