Trying to compile Botan configured as x86_64 with non-x86_64 compiler.

[crazydef]

Hi,

I'm getting the following error when including Botan headers in my project.

3rdParty/botan/build.h:428:6: error: "Trying to compile Botan configured as x86_64 with non-x86_64 compiler."
    #error "Trying to compile Botan configured as x86_64 with non-x86_64 compiler."

While I'm not using Botan on my target platform (WebASM via Emscripten) yet, I was planning on doing so at some point in the future. Do these errors imply I will need to have separate Botan repositories locally for every platform I want to target? Because that seems... extremely inefficient.
