CMake构建Qt工程

news2024/9/27 2:50:01

在https://blog.csdn.net/fengbingchun/category_12172633.html 上有直接通过vs2022建的Console、Widgets、Quick三个工程，这里增加通过CMake构建。

build.sh内容如下：

#! /bin/bash

if [ $# != 1 ]; then
    echo "Error: requires one parameter: Release or Debug"
    echo "For example: $0 Debug"
    exit -1
fi

if [ $1 != "Debug" ] && [ $1 != "Release" ]; then
    echo "Error: supported parameter values are only Debug or Release: $1"
    exit -1
fi

result_judgment()
{
    rc=$?
    if [[ ${rc} != 0 ]]; then
        echo -e "\033[0;31mError: there are some errors in the above operation, please check: ${rc}\033[0m"
        exit ${rc}
    fi
}

build_dir="build"
if [ ! -d ${build_dir} ]; then
    mkdir -p ${build_dir}
fi

cd build

cmake \
    -G"Visual Studio 17 2022" -A x64 \
    -DCMAKE_BUILD_TYPE=$1 \
    -DCMAKE_CONFIGURATION_TYPES=$1 \
    ..
result_judgment

cmake --build . --config $1
result_judgment

echo -e "\033[0;32mbuild finish\033[0m"

CMakeLists.txt内容如下：

cmake_minimum_required(VERSION 3.24.0)
project(Qt_Test)

message(STATUS "build type: ${CMAKE_BUILD_TYPE}")
message(STATUS "current source dir: ${CMAKE_CURRENT_SOURCE_DIR}")
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

set(CMAKE_PREFIX_PATH "C:/Qt/6.4.2/msvc2019_64/lib/cmake/Qt6") # Qt6Config.cmake file location

find_package(Qt6 REQUIRED COMPONENTS Core Gui Widgets Quick)
qt_standard_project_setup()

# Widgets_Test
set(SRCS_WIDGETS_PATH ${CMAKE_CURRENT_SOURCE_DIR}/../../demo/Widgets_Test)
set(SRCS_WIDGETS
    ${SRCS_WIDGETS_PATH}/main.cpp
    ${SRCS_WIDGETS_PATH}/Widgets_Test.cpp
    ${SRCS_WIDGETS_PATH}/Widgets_Test.ui
)

add_executable(Widgets_Test ${SRCS_WIDGETS})
target_include_directories(Widgets_Test PRIVATE ${SRCS_WIDGETS_PATH})
target_link_libraries(Widgets_Test PRIVATE Qt6::Widgets)
# set_target_properties(Widgets_Test PROPERTIES # no need
#     WIN32_EXECUTABLE ON
#     MACOSX_BUNDLE ON
# )

# Console_Test
set(SRCS_CONSOLE_PATH ${CMAKE_CURRENT_SOURCE_DIR}/../../demo/Console_Test)
aux_source_directory(${SRCS_CONSOLE_PATH} SRCS_CONSOLE)

add_executable(Console_Test ${SRCS_CONSOLE})
target_include_directories(Console_Test PRIVATE ${SRCS_CONSOLE_PATH})
target_link_libraries(Console_Test PRIVATE Qt6::Core)

# Quick_Test
#set(CMAKE_AUTOMOC ON) # no need

set(SRCS_QUICK_PATH ${CMAKE_CURRENT_SOURCE_DIR}/../../demo/Quick_Test)
set(SRCS_QUICK
    ${SRCS_QUICK_PATH}/main.cpp
)

add_definitions(-DCMAKE_BUILD_METHOD)

add_executable(Quick_Test ${SRCS_QUICK}) # you can also use qt_add_executable
target_link_libraries(Quick_Test PRIVATE Qt6::Gui Qt6::Quick)
#target_sources(Quick_Test PRIVATE ${SRCS_QUICK_PATH}/qml.qrc) # no need

生成的vs2022工程如下：

注：

1.Widgets_Test和Console_Test工程既可以调试运行也可以通过cmd运行；

2.运行Quick_Test需要做些改动：具体原因未知

(1).需要将demo/Quick_Test/main.cpp中的一条语句做调整，如下：

#ifdef CMAKE_BUILD_METHOD
    engine.load(QUrl(QStringLiteral("main.qml"))); // 使用CMakeLists.txt生成工程时需要使用此句
#else
    engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
#endif

(2).如果通过打开工程调试运行，需要将demo/Quick_Test下的main.qml和test.jpg拷贝到build目录下，即与Qt_Test.sln同一目录；

(3).如果直接通过cmd运行，需要将main.qml和test.jpg拷贝到Quick_Test.exe同一目录下。通过cmd运行结果如下：
