hello-libs native dependency not respected? #961

If I run this
$ git clone git@github.com:android/ndk-samples.git

I end up with an error like
> Task :app:buildCMakeDebug[arm64-v8a] FAILED
C/C++: ninja: error: '/ndk-samples/hello-libs/distribution/gmath/lib/arm64-v8a/libgmath.a', needed by '/ndk-samples/hello-libs/app/build/intermediates/cxx/Debug/141w5z33/obj/arm64-v8a/libhello-libs.so', missing and no known rule to make it
Since the cmake build in gen-libs doesn't run before the one in app, despite the dependency being specified.
When running with --info, I can see

So :gen-libs:buildCMakeDebug[arm64-v8a][gmath gperf] appears after :app:buildCMakeDebug[arm64-v8a].
If I run ./gradlew --info :app:assembleDebug I get

So, while some :gen-libs tasks are there, the CMake ones are not.
Somehow the
dependencies {
...
api project(':gen-libs')
}
doesn't seem to apply to the native builds.
Am I misunderstanding how this is supposed to work?
Is this a bug in the Android Gradle Plugin or in the example?
