如何在QuaZip中连接CMake库

Question

我的项目使用QuaZip库，我需要通过CMake构建这个项目。如何将这个库添加到CMakeLists中？从图书馆我需要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}
)

生成错误：

CMake警告at CMakeLists.txt:13 (find_package)：由于没有在CMAKE_MODULE_PATH中提供"Findquazip.cmake“，该项目要求CMake查找由"quazip”提供的包配置文件，但CMake没有找到。 无法找到由"quazip“提供的具有下列任何名称之一的包配置文件： quazipConfig.cmake quazip-config.cmake 将安装前缀"quazip“添加到CMAKE_PREFIX_PATH或将"quazip_DIR”设置到包含上述文件之一的目录中。如果"quazip“提供了一个单独的开发包或SDK，请确保它已经安装。 CMake Error at CMakeLists.txt:37 ( target_link_libraries )：target_link_libraries的关键字签名已经与目标"Archiver“一起使用。带有目标的target_link_libraries的所有使用都必须是All关键字或全纯文本。 关键字签名的用法如下：

• CMakeLists.txt:31 (target_link_libraries)

Answer 1

quazip的查找脚本名为FindQuaZip5.cmake (在安装期间重命名)。因此，要找到您需要使用的quazip

find_package(QuaZip5)

find脚本的含义在它的头上描述了：

# 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，为了在代码中使用quazip和zlib，添加以下几行：

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