After Dirk fixed the Android Travis build (sdkmanager does not understand yes), the Travis build are failing again (after, I think 2 successful runs). Remarkably, the Travis fail is also just after the apk is produced, so there might be a relation between my local fail and the Travis fail.

Yes, fully understand a curse word. I was so surprised by this failure
that I restarted that failing build multiple times, to see if it was a
stupid glitch somewhere, but no ...

I'm seeing that CMAKE_MAKE_PROGRAM thing, as well. Annoying, but easy to
To add a new Android build thing ... when I build libgit2 with ndk-14d,
I finally end up with one unresolved symbol (mmap64). So, I currently
build libgit2 with ndk 10e. Lots of things to find on the internet on
mmap64 stuff, but unclear to me, at this point, if it is a libgit2
problem or a NDK thing.

That was the file I had been looking at earlier ... there is a lonely
"doc" and the end of the following target (on my build):
/usr/bin/cmake -C <path stripped>/src/subsurface/Documentation
OUT=<path stripped>/src/subsurface-mobile-build-arm/Documentation/ doc
