According currently PHP Compatibility Coding Standard documentation you need to follow this steps:

1. Open your composer.json file and add the following lines to:

"require-dev": {
    "phpcompatibility/php-compatibility": "*"
},
"prefer-stable" : true,
"scripts": {
    "post-install-cmd": "\"vendor/bin/phpcs\" --config-set installed_paths vendor/phpcompatibility/php-compatibility",
    "post-update-cmd" : "\"vendor/bin/phpcs\" --config-set installed_paths vendor/phpcompatibility/php-compatibility"
}

2. run composer update

3. Test with ./vendor/bin/phpcs -p . --standard=PHPCompatibility
