Problem building with -DARM=TRUE

[wader]

Hello! i'm trying build with -DARM=TRUE with alpine linux via docker on an aarch64 host (mac book m3) but running into various build errors.

$ uname -a
Linux 00823b109f1f 6.6.16-linuxkit #1 SMP Fri Feb 16 11:54:02 UTC 2024 aarch64 Linux

$ mkdir build && cd build
$ cmake -DARM=TRUE ..
$ gcc --version
gcc (Alpine 13.2.1_git20231014) 13.2.1 20231014
