I followed the readme and tried to execute node main.js bootstrap, but the build fails early with the following error. @vgorloff any ideas how I can workaround that?

macos 11.3 with intel arch
node 12
xcode 12.5
cmake 3.19.4
ninja 1.10.2
ndk 21.3.6528147 properly linked to /usr/local/ndk

I guess thats the error:
