qt文档网站：
如果您使用Qmake创建makefiles，则将包括在需要时拨打MOC的构建规则，因此您无需直接使用MOC。
所以我遵循了官方的最小申请教程，并创建了：
// hello.cpp:
#include <QtGui>
#include <QApplication>
#include <QLabel>
int main(int argc, char **argv) {
QApplication app(argc, argv);
QLabel label("Hello, world!");
label.show();
return app.exec();
}
运行qmake -project
将其添加到qtproject.pro：
...
INCLUDEPATH += .
QT += gui
QT += widgets
...
运行 qmake，我得到了这个makefile：

，但我看不到moc，rcc和uic Incocations。他们在哪里？
您的项目dones不包含任何QObject衍生的自定义类，因此不需要运行moc。
最小示例(mywidget.h(：
#ifndef MYWIDGET_H
#define MYWIDGET_H
#include <QWidget>
class MyWidget: public QWidget {
Q_OBJECT
};
#endif
和您修改的hello.cpp：
#include <QtGui>
#include <QApplication>
#include "mywidget.h"
int main(int argc, char **argv) {
QApplication app(argc, argv);
MyWidget w;
w.show();
return app.exec();
}
如果您现在运行qmake -project和qmake，生成的Makefile将包含呼叫moc，例如
...
