Description

#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.

Contributor guide

Research direction
Examine how the fPIC flag is added in the CMake build system, then conditionally omit it for MinGW targets (e.g., by checking the compiler target or using a cmake variable). Look at existing cross compilation settings in the repo for guidance.
