Manually building C++ library in bazel (4.2.1) sandbox

Question

For a proof on concept I want to use a CMAKE library in a large bazel (4.2.1) project.

In my first attempt I build the library outside bazel by hand and am loading it using new_local_repository.

This lets my build the application but when running it I am getting random exceptions form the standard library such as std::length_error or std::bad_alloc (meaning if I run the same application multiple times I get randomly different exceptions). The application works without any problems outside of bazel.

So I am pretty convinced that the libraries used in bazel do not match the libraries outside which I built my CMAKE library with.

Because this is just a POC I don't want to migrate the whole library to bazel.

The easiest would be if I could just built the library by hand inside the bazel sandbox but it seems this feature got removed.

I am aware of https://github.com/bazelbuild/rules_foreign_cc, but setting this up seems like a larger project itself.
