MAC: Qt Cannot detect toolkit

How I can configure QT Project using Qt 5.12.1/Qt Creator 4.8.1
I need compile my project for mac os.
I tryed with QT Creator, then, below problem occur.

Or compile with below command.

qmake
make

But, below error is occur.

third_party/wfdbio.cpp:181:5: fatal error: assigning to 'char *' from
      incompatible type 'void *'
    SSTRCPY(wfdbpath, wfdbpath_init);
    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

                                     ^~~~~~~~~~~~~~~~

make: *** [objects/wfdbio.o] Error 1

Of course, I can change some code with typecast, ex.) char* to void*.
But, there are many macros, and codes, so, many code change is need for "remove type cast".
Of course, I used "-fpermissive" flags, and my project is compiled at Windows 10.

So, How I can compile my project without code change?
