Hi Răzvan,

A lot of applications have a build script (typically a
makefile) that sets the paths according to the particular
system's environment variables, what the build system
detects about the libraries and header files present, and
probably other factors. Writing portable software is deep
subject. Of course you can finesse the issue by writing code
in a dynamic language like Perl, Python, Ruby, etc.  But
even then, guaranteeing that all necessary resources for a
particular application are present isn't trivial.

Within any given distribution of Linux, changes to the file
system layout are comparatively rare, not generally driven
by marketing or a commercial need to push users into
something new.

ISTR Gobo has had a few changes over the years.
