Why CGo-based build targeting GOOS=wasip1 failed

Question

I cannot build a cgo-based project targeting GOOS=wasip1. Here is github repository helping reproduction.

Environment

• Go 1.22.4
• Debian 12

Output of go env command goes as

Project Layout

|-main.go         // depends on C-based bindings APIs
|-bindings
  |-bindings.c    // implementation of C-based bindings
  |-bindings.go   // adapters of C-based bindings APIs
  |-bindings.h    // headers of C-based bindings

Problem Reproduction

Building the project as

GOOS=wasip1 GOARCH=wasm go build -v -o hello-world.wasm .

produces errors as

package github.com/sammyne/wasip1-cgo-broken-build
        imports github.com/sammyne/wasip1-cgo-broken-build/bindings: build constraints exclude all Go files in /github.com/sammyne/wasip1-cgo-broken-build/bindings

Really appreciate if someone could help me out~
