When using manually added compilers from a NDK in an Android kit then running CMake will fail to find a package configuration for Qt 5. It fails with:

By not providing "FindQt5.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Qt5", but
  CMake did not find one.

Using the pre-installed NDK's compilers work fine.
