 In some cases (e.g. when using custom `prefix` during configuration), the TREXIO library might end up installed in a directory, which is absent in the default `$LIBRARY_PATH`.
 In order to link the program against TREXIO, the search paths can be modified as follows:
 
-`export LIBRARY_PATH=$LIBRARY_PATH:<path_to_trexio>/lib` 
+`export LIBRARY_PATH=$LIBRARY_PATH:<path_to_trexio>/lib`
 
 (same holds for `$LD_LIBRARY_PATH`). The `<path_to_trexio>` has to be replaced by the prefix used during the installation.
