[CMake] CMake/Ninja support in Qt Creator

[Wouter van Kleunen]

I had the following idea to speed up the building even more, if a tool 
can be build in ninja to list all files that need to be stat when 
building  a project. These files can be monitored by qtcreator and later 
be provided as input again to ninja. So my idea works as follows:

1. Build project using cmake + ninja
2. Get file list of all dependencies by using ninja (something like 
ninja -t deplist).
3. Monitor the files using qt creator + qfilesystemwatcher

When the user requests a rebuild:
4. Execute a ninja build command + provide the list of changed files. 
This way ninja won't have to stat any file.
5. Ninja builds

Is this feasible ?
