{
    "name": "libwebp",
    "build": {
        "srcFilter": [
            "+<src/**/*.c>"
        ],
        "unflags": [
            "-DHAVE_CONFIG_H"
        ]
    }
}

Your srcFilter expression is causing every C file to be ignored.

Just replace the library.json file with

{
    "name": "libwebp",
    "build": {
        "unflags": [
            "-DHAVE_CONFIG_H"
        ],
        "flags": [
            "-I."
        ]
    }
}
