NDK 17 error: treating warnings as errors

  E:/ndk/android-ndk-r17b/build//../sources/cxx-stl/llvm-libc++/include/sstream:621: warning: relocation refers to discarded section
  ././../../../src/lib_json/json_reader.cpp:625: warning: relocation refers to discarded section

  clang++.exe: error: linker command failed with exit code 1 (use -v to see invocation)
解決辦法：
在CMakeLists.txt里加入如下一行即可解決：
set(CMAKE_SHARED_LINKER_FLAGS "${CMAKE_SHARED_LINKER_FLAGS} -Wall -v -Wl,--no-fatal-warnings")

必須是上面的這種形式，不能是以下形式
set(CMAKE_SHARED_LINKER_FLAGS " -Wall -v -Wl,--no-warn-shared-textrel")
 ，這種還是不能解決問題，需要帶上${CMAKE_SHARED_LINKER_FLAGS}；
相當於是增加配置參數，+=
