Gradle - Compiling against a C++ submodule library - c++

Question

I'm trying to setup a C++ project that itself uses another (not gradle) C++ project.
Since the compilation doesn't require anything special I tried including the project as a submodule and compiling that library as a library through gradle itself.
To my knowledge I have set up the build script correctly like this:
// Project-Type
apply plugin: "cpp"
// IDEs
apply plugin: "visual-studio"
model {
visualStudio {
solutions.all {
solutionFile.location = "vs/${name}.sln"
solutionFile.withContent { TextProvider content ->
content.asBuilder().insert(0, "# GENERATED FILE: DO NOT EDIT\n")
content.text = content.text.replaceAll("HideSolutionNode = FALSE", "HideSolutionNode = TRUE")
}
}
}

Though when I run gradle build I get the following error:
Parallel execution is an incubating feature.
FAILURE: Build failed with an exception.
* What went wrong:
Could not determine the dependencies of task ':linkAnniReleaseExecutable'.
> No static library binary available for library 'openNN' with [flavor: 'default', platform: 'x64', buildType: 'release']
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
* Get more help at https://help.gradle.org
BUILD FAILED in 1s
Can anyone help me with what I'm doing wrong?
