They can choose for themself. They can either copy the contents to the 
CMakeLists.txt, or distribute another file and include it. CMake does not see 
the difference anyway.

macros.cmake is a very bad name, centainly if its end up in /usr/share/cmake. 
Also, copiing the content isn't hard, and will have the same result.

It is definitly not a library. In /usr/lib, there usually are only libraries. 
All the cmake-files CMake distribute also goes to /usr/share 
(/usr/share/cmake/Modules, to be more exact). Torcs-ng does have a somewhat 
strange default share-path, but that doesn't change the situation.

> - of course (you didn't say it, but ...) install the headers in "include"

No, but I did write the code for it:) Maybe include/torcs-ng is better because 
some names can be quite general and we don't want end up overwriting some 
important system header file.

Not only robot development is affected. It can also be used to install cars 
and tracks into the right place.
