So I have 4 examples I actually tried to document. These all use my fork/derivative of the Android-CMake toolchain, which I believe comes from OpenCV. (It had grown stale with later NDKs and I hit problems). All of these rely heavily on the external NDK module system (NDK_MODULE_PATH).
The first and easiest (most self contained) is: https://bitbucket.org/ewing/hello-android-almixer This one invokes ant via shell scripts outside CMake. I then recently got SDL building with CMake using the same techniques. https://bitbucket.org/ewing/sdl_android_cleanup This one doesn't invoke ant because it builds only a library. There was actually an intermediate project I helped build after ALmixer that this also drew from, JavaScriptCore, and I documented my procedure here: https://github.com/appcelerator/hyperloop/wiki/Building-JavaScriptCore-for-Android Once you have SDL built, and you set your NDK_MODULE_PATH directly, I have an Ant example and Gradle example. The ant one is just like Hello-Android-ALmixer. https://bitbucket.org/ewing/helloandroidsdl-ant https://bitbucket.org/ewing/helloandroidsdl-gradle The Gradle one is a lot of hacks. Google is ditching Ant/Eclipse for Gradle/IntelliJ, but their NDK support is even worse in the latter right now. Again, once you leave the NDK, all these things live outside CMake. I think it would be interesting to make CMake handle all of this, but I can't visualize it yet. But I hope others might be able to build on my work, like how I've built on Android-CMake. An aside, I noticed Gradle is painfully slow. Depending on how one does CMake integration, I'm not sure I want it. Just to invoke it and for it to figure out no real work needs to be done is measured in seconds for me.
