Expanding wildcards with qmake
Tuesday, March 26, 2013
I was always wondering why doing something like this never worked
SOURCES += *.cpp SOURCES -= excluded.cpp
excluded.cpp always stayed in
SOURCES. The thing is that when you add a new value to the list, it's just a string. Thus using wildcard in files names is nothing more but an asteriks character. And therefore using
-= operator will only remove exact strings. But today I found another undocumented function I've been looking for years!
$$files(glob)— Returns a list of files which match the specified glob pattern.
So now I can do
SOURCES += $$files(*.cpp) SOURCES -= excluded.cpp
and it actually works.
