Android: build system dependencies are wrong

Hi.
I observed this in QtBluetooth, but I suspect it is not related to bluetooth.
I am building for Android and test on my phone.

I have the following situation:

1. I configure qtconnectivity
2. I build "cmake --build ."
3. I run a test "ctest -V -R tst_large"
4. I change some code
5. I build again "cmake --build ."
6. I run the tests again "ctest -V -R tst_large"

The second test run still tests the unmodified code. Even though the build step seems to build everything again.

My workaround at the moment is to "rm -rf" the build folder. So after each code change, I nuke the build folder, then configure, build from scratch and then run the tests.
