Yes, we have to check if we did anything wrong here.

FYI, this prevented Xcos to run.

You are welcome.

This is a good question ;)
The reason is because we are following the FHS (Filesystem Hierarchy
Standard) norm. This is managed transparently by the autotools and it
requires a clear separation between library, binary and data files. 
Since is the content of contrib/ is only data files, the install system
is going to install them in the share/ directory.
