Question

我的项目使用QuaZip库，我需要通过CMake构建该项目。如何将此库添加到CMakeLists？从库中，我需要JlCompress

我的CMakeLists：

cmake_minimum_required(VERSION 3.6)
#set_property(GLOBAL PROPERTY USE_FOLDERS ON)
#set_property(GLOBAL PROPERTY PREDEFINED_TARGETS_FOLDER "cmake")

set(Boost_USE_STATIC_LIBS OFF)
set(Boost_USE_MULTITHREADED ON)

project(Archiver LANGUAGES CXX)

set(CMAKE_INCLUDE_CURRENT_DIR ON)

find_package(Qt5 REQUIRED COMPONENTS Core Widgets Gui)
find_package(zlib)
find_package(QuaZip5)
include_directories(${QUAZIP_INCLUDE_DIRS})

set(project_ui
    mainwindow.ui)
set(project_headers
    archive.h
    mainwindow.h)
set(project_sources
    main.cpp
    archive.cpp
    mainwindow.cpp)

qt5_wrap_ui(project_headers_wrapped ${project_ui})
qt5_wrap_cpp(project_sources_moc ${project_headers})

add_executable(${PROJECT_NAME} ${project_headers} ${project_sources} 
    ${project_sources_moc} ${project_headers_wrapped})

target_link_libraries(${PROJECT_NAME} 
    PUBLIC 
    Qt5::Core
    Qt5::Gui
    Qt5::Widgets
    ${QUAZIP_LIBRARIES}
)

构建错误：

CMakeLists.txt：13的CMake警告（find_package）：不提供   CMAKE_MODULE_PATH中的“ Findquazip.cmake”此项目已询问CMake   查找“ quazip”提供的程序包配置文件，但CMake   没有找到一个。

找不到“ quazip”提供的程序包配置文件   具有以下任何名称：
quazipConfig.cmake
quazip-config.cmake
将“ quazip”的安装前缀添加到CMAKE_PREFIX_PATH或进行设置   “ quazip_DIR”到包含上述文件之一的目录。如果   “ quazip”提供了单独的开发包或SDK，请确保它   已安装。

CMakeLists.txt：37（target_link_libraries）的CMake错误：   target_link_libraries的关键字签名已用于   目标“归档”。将target_link_libraries与   目标必须是全关键字或全格式。

此处使用了关键字签名：


CMakeLists.txt：31（target_link_libraries）

Answer 1

quazip的查找脚本名为FindQuaZip5.cmake（在安装过程中重命名）。因此，要查找quazip，您需要使用

find_package(QuaZip5)

查找脚本的含义在其头部进行了描述：

# QUAZIP_FOUND               - QuaZip library was found
# QUAZIP_INCLUDE_DIR         - Path to QuaZip include dir
# QUAZIP_INCLUDE_DIRS        - Path to QuaZip and zlib include dir (combined from QUAZIP_INCLUDE_DIR + ZLIB_INCLUDE_DIR)
# QUAZIP_LIBRARIES           - List of QuaZip libraries
# QUAZIP_ZLIB_INCLUDE_DIR    - The include dir of zlib headers

也就是说，要在您的代码中将quazip与zlib一起使用，请添加以下行：

include_directories(${QUAZIP_INCLUDE_DIRS})
target_link_libraries(${PROJECT_NAME} ${QUAZIP_LIBRARIES})
