我想在Android Studio的assimp项目中实现NDK库，一切正常，但是一旦我尝试使用材质，就会出现以下错误：
assimp/types.h:208:19: error: taking address of packed member 'r' of class or structure 'aiColor3D' may result in an unaligned pointer value [-Werror,-Waddress-of-packed-member]
return *(&r + i);
这是CMakeLists个标志
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=gnu++11 -Wall -Werror")
