1.概要

创建工程的时候，如果每个文件都手动写入到工程中很麻烦，如下

add_executable(untitled4
  main.cpp
  a.h a.cpp
)

上面的a.h a.cpp有多少文件就添多少，如果文件多了很麻烦，其实可以用cmke提供的file函数解决这个问题，如下：

file (GLOB MAIN_SRC
        ${CMAKE_CURRENT_SOURCE_DIR}/*.cpp
        )

file (GLOB MAIN_HEADERS
        ${CMAKE_CURRENT_SOURCE_DIR}/*.h
        )

add_executable(untitled4
  main.cpp
  ${MAIN_SRC} ${MAIN_HEADERS}
)

2.代码

1.工程文件

2.A头文件

#ifndef A_H
#define A_H

class A
{
public:
    A();
};

#endif // A_H

3.A源文件

#include "a.h"
#include <QDebug>

A::A() {
    qDebug()<<"a structure";
}

4.主函数

#include <QCoreApplication>
#include <QDebug>
#include "a.h"

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    A a1;
    qDebug()<<"ddd";
    return a.exec();
}

5.工程文件

1.自动生成的

cmake_minimum_required(VERSION 3.14)

project(untitled4 LANGUAGES CXX)

set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

find_package(QT NAMES Qt6 Qt5 REQUIRED COMPONENTS Core)
find_package(Qt${QT_VERSION_MAJOR} REQUIRED COMPONENTS Core)

add_executable(untitled4
  main.cpp
  a.h a.cpp
)
target_link_libraries(untitled4 Qt${QT_VERSION_MAJOR}::Core)

include(GNUInstallDirs)
install(TARGETS untitled4
    LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR}
    RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR}
)

2.我改的

cmake_minimum_required(VERSION 3.14)

project(untitled4 LANGUAGES CXX)

set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

find_package(QT NAMES Qt6 Qt5 REQUIRED COMPONENTS Core)
find_package(Qt${QT_VERSION_MAJOR} REQUIRED COMPONENTS Core)

file (GLOB MAIN_SRC
        ${CMAKE_CURRENT_SOURCE_DIR}/*.cpp
        )

file (GLOB MAIN_HEADERS
        ${CMAKE_CURRENT_SOURCE_DIR}/*.h
        )

add_executable(untitled4
  main.cpp
  ${MAIN_SRC} ${MAIN_HEADERS}
)
target_link_libraries(untitled4 Qt${QT_VERSION_MAJOR}::Core)

include(GNUInstallDirs)
install(TARGETS untitled4
    LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR}
    RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR}
)

3.运行结果

09:11:03: Debugging D:\projects\qts\untitled4\build\Desktop_Qt_6_7_2_MinGW_64_bit-Debug\untitled4.exe ...
a structure
ddd
