cmake --build . gives error: "implicit declaration of function 'emb_fwrite'"

[sercan5534]

I'm not a C/C++ guy, but I followed steps on Readme:

• first checkout the repo with current branch
• than, I execute "cmake ."
• When I try to execute "cmake --build .", it gives me: ^
  /Users/sercanozen/libembroidery/src/pattern.c:906:5: error: implicit declaration of function 'emb_fwrite' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
  emb_fwrite(&flagsToWrite, 1, file);
  ^
  I'm using Mac M1(silicon) and I searched "emb_fwrite" function and didn't found anywhere.
