Cross-compilation build Linux to Windows Error - Forward slashes in paths converted to Backslashes

Build failing for windows/mingw target. Nimble project structure: src/wasm.nim:

import wasm3
let
  env = loadWasmEnv(readFile"wasm_payload.wasm")
  read_at_place = env.findFunction("read_wasm_at_index")
echo read_at_place.call(uint32, 0)

wasm.nimble:

After hammering the correct source paths into wasm3c.nim, eventually got another error of the same kind in a different C source file:

Fix seems simple, just don't change the source files path to backslashes if compiling on Linux.
