Hi,
I create a patch for removing the workaround for mbed-crypto building:
https://review.trustedfirmware.org/c/trusted-firmware-m/+/3022
We tried on cmake 3.7 and 3.10 with cygwin and it works; can some Cygwin/mingw user pick this patch and test if it could work in your side?
Thanks for your contribution 😊
