Dear Maria,

if you're following a tutorial (say, the one at
https://docs.einsteintoolkit.org/et-docs/Simplified_Tutorial_for_New_Users),
please open a ticket to report which set of instructions do not work on
your system.

For instance, are you using Simfactory? Where exactly did you modify
CPPFLAGS?

Best,
Eloisa
