我已经在Visual Studio 2015 x64中成功编译和构建了ilmbase-2.2.1库。但我在链接dwaLookups项目（调试和发布）方面遇到了问题。该项目具有以下预处理器定义
WIN32
_WINDOWS
_DEBUG
HAVE_CONFIG_H
ILM_IMF_TEST_IMAGEDIR="D:/SDK/OpenEXR/openexr-2.2.1/IlmImfTest/"
OPENEXR_DLL
ILMIMF_EXPORTS
CMAKE_INTDIR="Debug"
运行时库设置为多线程调试DLL（/ MDd）并链接以下库的调试版本 Half.lib，Iex-2_2.lib，IlmThread-2_2.lib
项目有以下链接错误
