Emscripten has deprecated their linker flag 'BINARYEN_METHOD' and mentioned that in the changelog:
v1.38.23: 01/10/2019
Remove BINARYEN_METHOD: no more support for interpret modes, and if you want non-wasm, use WASM=0.
It was simply removed from CMaeLists.txt file as it already has 'WASM=0' for asmjs and 'WASM=1' for wasm.
