'No rule to make target `main.o' ' when using wildcards with qmake SOURCES variable

Create simple hello world application. Move main.cpp to src/main.cpp.
Add SOURCES += src/*.cpp to .pro file.
Try build main.cpp file - error: No rule to make target `main.o'. Stop.
Try build project - error: No rule to make target `Src/*.cpp', needed by `*.o'. Stop.

SOURCES += src/main.cpp - builds ok.

Temporal workaround would be appreciated. Not using wildcards is not a case.
