Browse Source 
- `-pie` is only valid when linking executables (PIE), not shared
  libraries. So remove `-pie` from shared libraries linker flag.

Subject: [PATCH] CMakeLists: fix build failure by removing -pie from shared
library targets
With CMake 4.1.0 the build of libipmctl started failing with:
error: undefined reference to `main` in *.S
- `-pie` is only valid when linking executables (PIE), not shared
libraries.
- When applied to a shared library, the linker expects a `main`
symbol, causing the undefined reference error.
- Remove `-pie` from shared libraries linker flag
