注意引用动态库文件
工程文件加入LIB += *.lib文件
加入加入库:
win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../DllTest-build-Desktop_Qt_5_0_0_MSVC2010_32bit_SDK-Debug/release/ -lDllTest
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../DllTest-build-Desktop_Qt_5_0_0_MSVC2010_32bit_SDK-Debug/debug/ -lDllTest
INCLUDEPATH += $$PWD/../DllTest-build-Desktop_Qt_5_0_0_MSVC2010_32bit_SDK-Debug/debug
DEPENDPATH += $$PWD/../DllTest-build-Desktop_Qt_5_0_0_MSVC2010_32bit_SDK-Debug/debug
