WheelBuilder copies from first folder named "lib.*" - which may not be the correct one

[robbotorigami]

• Poetry version: poetry-core==1.7.0

• I am on the latest stable Poetry version, installed using a recommended method.
• I have searched the issues of this repo and believe that this is not a duplicate.
• I have consulted the FAQ and blog for any relevant entries or release notes.

Issue

in the WheelBuilder._build method the built library folder is detected by looking for the first folder matching lib.*:

libs: list[Path] = list(build_dir.glob("lib.*"))
...
lib = libs[0]

This works on a clean build, but may cause issues for a project with multiple build targets. E.g. on a project I have, the build directory looks like:

build
    > lib.linux-x86_64-cpython-39
    > lib.linux-x86_64-cpython-311

When a wheel is built targeting 3.11, poetry-core will incorrectly include the 3.9 libraries.

This probably isn't a high-priority issue since there's an easy work-around of just ensuring your build directory is cleaned prior to building the wheel.

If I have time later this week I can probably make a fix/PR for this issue.

related #6197 in which generated files are put in plain lib and consequently omitted from the package - if you intend to tackle this then it would be good to kill two birds with one stone
