How to Reference Shared Library from cmake?

Hi, if I’m trying to set an environment variable within cmake for rules_foreign_cc
based on the output of another shared_lib generated by cmake, what would be the proper way to do so?

cmake(
name = "lib",
cache_entries = {
"path_to_shared_lib": ""
}
)

cmake(
name = "fake",
...
out_shared_libs = [
"libfake.so",
],
visibility = ["//visibility:public"],
)

Start by investigating the rules_foreign_cc CMake integration, especially how cache_entries relates to outputs declared with out_shared_libs. The issue names no source files or tests, so first determine the supported way to pass the generated libfake.so path into another cmake rule; done means documenting a verified configuration or clarifying that it is unsupported.
