The first goal of this commit was to ensure that the LD_LIBRARY_PATH setting performed in some of the generated scripts uses absolute paths, otherwise if a process (such as ctest) changes the current directory before starting an executable that needs our LD_LIBRARY_PATH setting, we can have problems (thanks to Patrick Callahan for the report). Some refactoring of the automated script generation plus a few other fixes concerning these scripts were done along the way (use here documents for better readability; don't use 'echo' with options as this is non-portable; etc.).
