You should have a structure like this:

   -rootApp
    |--build.gradle
    |--settings.gradle
    |--app
    |----build.gradle

    -rootMessage
    |--build.gradle
    |--settings.gradle
    |--vcard
    |----build.gradle

Inside a project you can refer an external module.

Just use:

In rootApp/settings.gradle:

include ':app' 
include ':myExternalLib'
project(':myExternalLib').projectDir=new   File('/path-to-project/rootMessage/vcard')

In app/build.gradle:

dependencies {
    implementation project(':myExternalLib')
}

Pay attention to myExternalLib.
You have to use the path of the library inside the other project, not the root of the project.
In your case the path is rootMessage/vcard.
Also,the rootMessage/settings.gradle will not be read because you are using the rootApp project.
