获取软件包（FetchContent） (CMake 3.11+)

添加子目录

编译时的一些坑
add_compile_options(-std=c++11)
add_compile_options(-fPIC)
add_definitions(-D_GLIBCXX_USE_CXX11_ABI=0)
默认D_GLIBCXX_USE_CXX11_ABI应该是1，导致编译出来的string函数符号不对，含有cxx1112basic_stringIcSt11char，改成0就好了
编译出来的符号是std::__cxx11::string而库符号是std::string，也可以尝试通过重设ABI=0解决。

add_library(lib_mkldnn SHARED IMPORTED)

configure_file(input output options) 将一个文件拷贝到指定位置，并根据options修改其内容。
