Failing to link boost libs on Make

**Version of emscripten/emsdk:**
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 3.1.10 (c3fe57af0504fe24fc4ba697feb8c204f3c80022)
clang version 15.0.0 (https://github.com/llvm/llvm-project 8bc29d14273b05b05d5a56e34c07948dc2c770d3)
Target: wasm32-unknown-emscripten
Thread model: posix
InstalledDir: /root/emsdk/upstream/bin

I followed the last comment for building boost with emscripten before compiling/linking with my sample project:
