[Princein]

I developed a Qt project on Mac which transplanted from Windows Qt,everything is working fine in Windows Qt,but in Mac Qt show many errors, one of them is :
'fbxsdk.h' file not found
it seem to say I have not add FBX SDK to my Mac Qt project. so I add it according official website: https://help.autodesk.com/view/FBX/2017/ENU/?guid=__files_GUID_724E9FAD_AFA0_4348_BDAA_6CF2FDF2FF55_htm .

and study add FBX SDK in Windows Qt project in this website : https://forums.autodesk.com/t5/fbx-forum/including-sdk-to-qt-creator/td-p/8184654 .

so I edit my .pro, the content is here :

LIBS += /Applications/Autodesk/FBX\ SDK/2019.2/lib/clang/debug/libfbxsdk.a
LIBS += /Applications/Autodesk/FBX\ SDK/2019.2/lib/clang/debug/libfbxsdk.dylib
INCLUDEPATH += /Applications/Autodesk/FBX\ SDK/2019.2/include
DEPENDPATH += /Applications/Autodesk/FBX\ SDK/2019.2/lib/clang

it still show error : 'fbxsdk.h' file not found, how should I add FBX\ SDK in my Mac Qt project,thanks a lot!
