Changing current directory is kind of evil, better they where you are
and just open the files from whereever they are, the tricky part is
always to find out where they are, since programms in linux are very
often launched from PATH. Most programms use ugly evil hardcoded paths
in the binary. Luckily the /proc filesystem provides the absolute
location of an executable, so no need for hardcompiled stuff, code
looks like:

	char exe_file[PATH_MAX];
	if (readlink("/proc/self/exe", exe_file, PATH_MAX) < 0)
	{
		throw CL_Error(strerror(errno));
	}
	else
	{
		return std::string(dirname(exe_file)) + "/";
	}
