qt creator - Qt - Using asterisk (*) in .pro-File with directories

Question

I have a .pro file which looks like:

SOURCES += myfolder/source1.cpp 
           myfolder/source2.cpp
HEADERS  += myfolder/header1.h
            myfolder/header2.h
FORMS    += myfolder/form1.ui
            myfolder/form2.ui

And everything works great. However, if I try to use an asterisk to include all the files, i.e.:

SOURCES  += myfolder/*.cpp
HEADERS  += myfolder/*.h
FORMS    += myfolder/*.ui

qmake throws a file-not-found-error:

WARNING: Failure to find: myfolder*.cpp
[...]
:-1: error: No rule to make target `myfolder/*.cpp', needed by `release/source1.o'.  Stop.

In both cases, Qt-Creator can find the files.

Is there a way to use the asterisk? It's annoying to type the files manually.

Thank you!

Answer 1

In qmake 3.0, at least, it's possible to use something like:

SOURCES = $$files(*.cpp, true)
HEADERS = $$files(*.h, true)

The true argument will cause the files function to recursively find all files matching the pattern given by the first argument.
