描述

#1910 adds mingw cross compilations, and tests it in CI. But only CLI generation is tested.

The issue is, library compilation generates warnings related to -fPIC compilation flag. Since tests follow a zero-warning policy, running such a test would break CI.

The goal is to find a way to cross-compile libzstd with mingw without generating warnings.

研究方向
First, examine the existing PR #1910 to understand how mingw cross compilation is set up for CLI. Then look at the library build process, likely in Makefile or CMakeLists.txt, to identify where fPIC flag is added and why it causes warnings for mingw. The goal is to conditionally disable fPIC for Windows targets (mingw) without affecting other platforms. Ensure that the CI test for library compilation is also added.
