Check for existing custom target: uninstall

Browse Source 
When including `cppkafka` in a CMake project containing other project defining the same target (`curl`, specifically, which defines the same target [here](3ea7679057/CMakeLists.txt (L1293))) I get the foollowing error:

```
add_custom_target cannot create target "uninstall" because another target  with the same name already exists
```

This if condition fixes the issue.
