'tools/tiny_ssim.wasm': No such file or directory

Hello,

I'm trying to compile this wonderful project. I'm using docker. Even though I pulled the latest emsdk and libvpx projects, but still keep getting error as below and get no lucky, because I'm new in compiling.

--enable-shared is only supported on ELF; assuming this is OK

Here below is my steps. Any help would be appreciate.
