Building folly
cc @rdtscp
Building facebook/folly also requires a built Boost, which we simply don't have. But it's also not possible to install Boost using folly's getdeps.py, because that uses system defaults and won't result in correct static library binaries for every compiler.
So for now I'd say we should just use header only until we can build boost ourselves.
We do have boost now, can be downloaded for a specific compiler by using for example the url https://conan.compiler-explorer.com/downloadpkg/boost_bin/1.85.0/arm64g1320 where arm64g1320 is the compiler id that we use.
Except for Clang when it could successfully build against libc++, we might need a solution for that first.
Hi! Folly should be able to build against libc++ now. Maybe this can move forward.
