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         


        

Answer 1

At first, using asterisk is bad practice - despite that qmake allows it, QtCreator cannot edit such *.pro correctly on adding new, renaming or deleting file. So try to add new files with "New file" or "Add existing files" dialogs.

QMake has for loop and function $$files(directory_path: String). Also append files to SOURCES or HEADERS variable respectively.

Brief example, which adds all files, but not directories, to variable FILES (not affect build or project tree):

files = $$files($$PWD/src)
win32:files ~= s|\\\\|/|g
for(file, files):!exists($$file/*):FILES += $$file

If you want to check if file is *.cpp, try to use contains($$file, ".cpp").

files = $$files($$PWD/src)
win32:files ~= s|\\\\|/|g
for(file, files):!exists($$file/*):contains($$file, ".cpp"):SOURCES += $$file
