CMake/Android error: "not able to compile a simple test program"

I am trying to compile a CMake project for android.

I use QtCreator to create and compile the project. Using QMake works fine, but CMake projects don't work.

CMake Project parsing failed.

CMake Project parsing failed.

I found several posts about this, but most of them were not answered or simply not useful. I found this helpful, so I added

SET (CMAKE_C_COMPILER_WORKS 1)
SET (CMAKE_CXX_COMPILER_WORKS 1)

before project(). But now I get

CMake Error in CMakeLists.txt:
  No known features for CXX compiler

  "Clang"

  version 8.0.2.


CMake Project parsing failed.

So far I haven't found something useful for that.

I hope I can get some more help this way.

ps: I recently reinstalled my os (Windows 10), so if I forgot to update something it's not older than two month. I let QtCreator, Visual Studio and Android Studio do the installation of the toolchains.

pps: The project is a new project created by QtCreator
