In the last few commits the problem occured
that absolute paths are needed for correct
and unambiguous locations for binary files
or the database.
For the compiler arguments the problem is now
solved with an automatic script, that creates
the absolute paths automatically for different
systems.
The database path is now specified by calling
a new function, that finds the root of the
project followed by a relative path.
The tests where cluttering the src dir
so i moved them to a separate dir.
Same goes for the binaries so i changed the
outputdirectory for them and
added these to the new gitignore file
