All c/c++ programs can be compiled to Wasm without any xmake.lua configuration changes, just switch to the wasm compilation platform and compile.

$ xmake f -p wasm
$ xmake

For detailed wasm compilation configuration see: wasm configuration

Alternatively, when compiling a file with the -preload-file assets/xxx.md setting, we can also simplify its setup by configuring

target("test5")
    set_kind("binary")
    add_files("src/*.cpp")
    add_values("wasm.preloadfiles", "src/xxx.md")
    add_values("wasm.preloadfiles", "src/xxx2.md")
