Hello,
I have packaged libbson via the
mongo-c-driver(https://github.com/mongodb/mongo-c-driver) but am having a
curious issue with the pkg-config files generated as part of its CMake build
system. It has two outputs, shared and static, but both pkg-config files
include static glibc in their "Libs:" which are accessed via `pkg-config --libs
...`. Thus, when attempting to use the package in compiling a dynamic
executable, the static glibc is linked in, causing immediate segfaults upon
execution.
I am wondering if anyone more familiar with cmake-build-system or CMake as a
whole has any ideas about why the static glibc is ending up as the associated
lib instead of the shared version. I am on commit `bb73faea` of Guix.
The guix package:
```
(use-modules
((guix licenses) #:prefix licenses:)
(guix build-system cmake)
(guix git-download)
(guix packages))
(define-public libbson
(package

(home-page "https://github.com/mongodb/mongo-c-driver";)

,(string-append "-DBUILD_VERSION=" "1.27.2"))))

```
The pkg-config file for the shared output of libbson:
```
# pkg-config .pc file generated by CMake 3.24.2 for libbson-1.27.2. DO NOT EDIT!
