For UNIX libraries staring with **lib**, like *libmath.a*, this tool will collect the library name **math**.
For UNIX libraries starting with **lib**, like *libmath.a*, this tool will collect the library name **math**.

Regarding symlinks, this tool will keep only the "most generic" file among the resolved real file and all symlinks pointing to this real file.
For example among files below, this tool will select *libmath.dylib* file and therefore only append *math* in the returned list:

.. code-block:: shell

-rwxr-xr-x libmath.1.0.0.dylib
lrwxr-xr-x libmath.1.dylib -> libmath.1.0.0.dylib
lrwxr-xr-x libmath.dylib -> libmath.1.dylib

**Parameters:**
- **conanfile** (Required): A ``ConanFile`` object to get the ``package_folder`` and ``cpp_info``.
