Description
When you run Cmake version 3.11.2 you get this error:
```
CMake Warning (dev) in src/CMakeLists.txt:
Policy CMP0071 is not set: Let AUTOMOC and AUTOUIC process GENERATED files.
Run "cmake --help-policy CMP0071" for policy details. Use the cmake_policy
command to set the policy and suppress this warning.
For compatibility, CMake is excluding the GENERATED source file(s):
"/home/pj/Desktop/lmms/build/src/embedded_resources.h"
from processing by AUTOMOC. If any of the files should be processed, set
CMP0071 to NEW. If any of the files should not be processed, explicitly
exclude them by setting the source file property SKIP_AUTOMOC:
set_property(SOURCE file.h PROPERTY SKIP_AUTOMOC ON)
```
[This](https://cmake.org/cmake/help/latest/policy/CMP0071.html) is the policy that isn't being set, and is similar to #3985. I can make a pull request to fix this.
