Creator litters source directory

Creator creates files in my source directory. If I am building my project from command line the source directory remains clean. If I open the project with QtCreator the following empty files are in my source directory, though it is an out of source build:

.cmake/api/v1/reply
.cmake/api/v1/query/cmakeFiles-v1
.cmake/api/v1/query/codemodel-v2
.cmake/api/v1/query/cache-v2

The Kit requests not to run CMake automatically. To me it looks like CMake server does magic stuff. As a workaround  .cmake can be put in .gitignore. Without a fix many project teams around the world are wasting time trying to find out where these files come from.
