Nice, but it doesn't catch the documentation for each macro/function. It only
takes the top documentation strings of each .cmake file.

Hi Peter

my be an Idea for further improvements of the cmake handling:

If the orocos_use_package was not able to find the requested package it is not complaining. It will simply not print out the message "found . .." If possible I would prefer to get a warning/error that the requested package could not be found.

I find it always hard to look for missing messages instead for warnings/error messages.
