Can't compile for Linux nor MacOS from Windows 10 machine

I'm trying to compile a linux library with the following command:
`scons platform=linux target=debug generate_bindings=yes use_llvm=yes bits=64 -j4`
However, every time I try, it complains about clang++ not being recognized.

```
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...

```

I **know** I have clang++ properly installed because the clang++ command works in any old terminal!
I'd love some help to figure out why this happens.
