[cmake-developers] Source code ///! comments

[Sebastian Holtermann]

Looking through the source code I found various comments
starting with "///!"

E.g.:
```
///! myFunction description
myFunction()
```

To my blame, I've use it as well.  But is this a valid meta notation?
If Doxygen is targeted, the comment should start with either "///" or
"//!".  When the comment starts with "///!", the exclamation mark ends 
up in the comment text. This looks very wrong in the few cases I've checked.

For reference

Any ideas?
