gwyddion @2.55: build failure on Big Sur

[GTTS2020]

Hi, I am trying to install Gwyddion but this is what I get:

Does someone have any suggestion? Please, consider that I am at level zero with coding...so be simple please!

Presumed duplicate of #61720 since this was on Big Sur and that issue would affect all Big Sur users.
