如何在CMake中连接QuaZip库 [英] How to connect the QuaZip library in CMake

问题描述

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

My project uses the QuaZip library, and I need to build the project through CMake. How to add this library to CMakeLists? From the library I need JlCompress

我的CMakeList：

My 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：

在CMakeLists.txt：13（find_package）上发出CMake警告：通过在项目CMAKE_MODULE_PATH中不提供
Findquazip.cmake CMake
找不到 quazip提供的软件包配置文件，但是CMake
找不到一个。

CMake Warning at CMakeLists.txt:13 (find_package): By not providing "Findquazip.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "quazip", but CMake did not find one.

找不到软件包配置文件由 quazip
提供，并具有以下任何名称：

Could not find a package configuration file provided by "quazip" with any of the following names:

quazipConfig.cmake
quazip-config.cmake

将 quazip的安装前缀添加到CMAKE_PREFIX_PATH或设置
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，请确保已安装
。

Add the installation prefix of "quazip" to CMAKE_PREFIX_PATH or set "quazip_DIR" to a directory containing one of the above files. If "quazip" provides a separate development package or SDK, be sure it has been installed.

CMakeLists.txt上的CMake错误：txt：37 （target_link_libraries）：target_link_libraries的
关键字签名已与
目标存档器一起使用。具有
目标的target_link_libraries的所有使用都必须是全关键字或全部使用。

CMake Error at CMakeLists.txt:37 (target_link_libraries): The keyword signature for target_link_libraries has already been used with the target "Archiver". All uses of target_link_libraries with a target must be either all-keyword or all-plain.

关键字签名的使用在这里：

The uses of the keyword signature are here:

• CMakeLists.txt：31（target_link_libraries）

推荐答案

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

The find script for quazip is named FindQuaZip5.cmake (it is renamed during installation). So for find quazip you need to use

find_package(QuaZip5)

查找脚本的含义在其头部进行了描述：

Meaning of the find script is described in its head:

# 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，要在代码中将 quazip 与 zlib 一起使用，请添加以下行：

That is, for use quazip with zlib in your code, add these lines:

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