我尝试使用CMake和GCC（G++）在Ubuntu上构建我的共享库，但每次都出现链接器错误。但是当我把我的库编译成静态库时，它构建得很好。此外，当我在Windows上构建它时，它可以作为共享库和静态库编译得很好。
Linker error看起来像这样：

usr/bin/ld: Dependencies/GLAD/libGLAD.a(gl.c.o): warning: relocation against glad_glNamedFramebufferReadBuffer' in read-only section .text'
/usr/bin/ld: CMakeFiles/Soul-Byte-Engine-Core-Window-Manager-obj.dir/Sources/WindowManager.cpp.o: relocation R_X86_64_PC32 against symbol `_ZSt4cout@@GLIBCXX_3.4' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: bad value
