How do I clean up the project files generated by CMake?

Question

I am using CMake to generate the project files. Is there a command with which I can clean up all those generated project files?

Accepted Answer

Is there a command with which I can clean up all those generated project files?

Yes - if you do an out-of-source build (as recommended).

To do so, create a directory - for example, `build` - within your projects directory and run CMake from there:

```
mkdir build
cd build
cmake ..
make
```

(Or tell your IDE to do so.)

Now all generated files are within `build`. To clean those, just remove the directory (`rm -rf build`).

PRO: You can keep all generated files out of your versioning system by adding `build` to its ignore ;-)
