List files in sub-directories with QDir's filter

I'm looking for a function similar to the python glob function.

If my folder structure is:
folder1/abc1.txt
folder1/xyz1.txt
folder1/abc2.txt
folder2/abc3.txt
folder2/xyz4.txt
folder3/abc5.txt

then if I give */abc*, I'm looking for an output of:

folder1/abc1.txt
folder1/abc2.txt
folder2/abc3.txt
folder3/abc5.txt

I tried entrylist, but it just lets me filter on what's in the current folder.

You can of course traverse recursively with an embedded loop like this:

main.cpp

#include <QDir>
#include <QFileInfoList>
#include <QString>
#include <QStringList>
#include <QDebug>

void traverse(const QString &pattern, const QString &dirname, int level)
{
    QDir dir(dirname);
    dir.setFilter(QDir::Dirs | QDir::Files | QDir::NoSymLinks | QDir::NoDot | QDir::NoDotDot);

    static const QStringList stringList = pattern.split('/');
    foreach (QFileInfo fileInfo, dir.entryInfoList(stringList.mid(level, 1))) {
        if (fileInfo.isDir() && fileInfo.isReadable())
            traverse(pattern, fileInfo.filePath(), level+1);
        else if (stringList.size() == (level + 1))
            qDebug() << fileInfo.filePath();
    }
}

int main()
{
    traverse("*/abc*", ".", 0);
    return 0;
}

main.pro

TEMPLATE = app
TARGET = main
QT = core
SOURCES += main.cpp

Build and Run

qmake && make && ./main

Output

"./folder1/abc1.txt"
"./folder1/abc2.txt"
"./folder2/abc3.txt"
"./folder3/abc5.txt"
