问题：can not be used when making a shared object; recompile with -fPIC

spdlog/lib/libspdlog.a(spdlog.cpp.o): relocation R_X86_64_TPOFF32 against `_ZGVZN6spdlog7details2os9thread_idEvE3tid' can not be used when making a shared object; recompile with -fPIC

解决：cmake 添加 fpic参数

set（CMAKE_C_FLAGS“$ {CMAKE_C_FLAGS} -fPIC”）
set（CMAKE_CXX_FLAGS“$ {CMAKE_CXX_FLAGS} -fPIC”）
