Powered by .NET 6 on Kubernetes 以向导的方式运行CMake。此选项会弹出一系列的提示，要求用户回答关于工程配置的一些问题。这些结果会被用来设置cmake的缓存值。注意，新版的CMake可能不再支持此选项。, -E： 可选命令，为Ninja生成器指定一个.d depfile。 .d文件保存通常由自定义命令本身发出的依赖关系。对其他生成器使用DEPFILE是一个错误。, 参数介绍： For some online demos and documentations, make sure … 3. generator. add_executable() command), it will automatically be replaced Bug 6084 - __xxx__ not interpreted as markdown when xxx begins with a non-word character (e.g. 指向当前编译工程构建的全路径。, 有了上面的基础，再编写CMakeLists.txt自然会事半功倍。下面，以几个小实例来说下通过CMakeLists.txt的来构建项目。, 这里cJSON库为例来说明下CMakeLists.txt的写法。当然，这里的代码并严谨，仅用来演示CMakeList的用法。, (1)在本地建立cJSONdemo1的目录工程，并将cJSON库源代码拷贝到目录中，并在该目录新建CMakeLists.txt文件。目录结构如下：, (2)自动搜索目录源码 generator expressions, but not necessarily composed into a stateful shell or batch script. command is an abstraction for the necessary build/make call. CMake全称为“cross platform make”，是一个开源的跨平台自动化构建系统。使用指定名为CMakeLists.txt的配置文件可以控制软件的构建、测试和打包等流程。同时，通过编写平台无关的CMakeLists.txt文件和需要简单的配置，CMake就能生成对应目标平台的构建文件，例如：类Unix系统的makefile文件、Windows的Visual Studio工程或者Mac的Xcode工程，大大简化了跨平台和交叉编译方面的工作。, 当然，类似的make工具也很多，Autocof、JAM、QMake、SCons甚至ANT，目的都是指定一套规则来简化整个构建编译流程。CMake工具链简单、灵活，且跨平台，很多知名项目都在使用CMake构建。适合以C、C++或者java等编译语言的项目。, CMake的安装过程很简单，这里就不再赘述了。其中CMake提供带GUI界面的工具cmake-gui。本文主要是以命令行的形式来讲述CMake的使用，这里就稍微提一下cmake-gui的使用。原理都是差不多的。, 简述操作步骤如下： CMake is part of a family of tools designed to build, test and package software. Eg, # GIT_REPOSITORY github.com:google/googletest.git, "${CMAKE_CURRENT_BINARY_DIR}/googletest-src", "${CMAKE_CURRENT_BINARY_DIR}/googletest-build". Specified source files will be added to IDE project files for Adds a target with the given name that executes the given commands. This section will focus on inspecting build types and their corresponding compiler flags. 该命令调用列出的源文件来构建的可执行目标。 对应于逻辑目标名称，在项目中必须是全局唯一的。构建的可执行文件的实际文件名是基于本机平台的约定。, WIN32： 指定要在构建时执行的命令行。如果指定多个COMMAND，它们讲按顺心执行。ARGS参数是为了向后兼容，为可选参数。args1和args2为参数，多个参数用空格隔开。, BYPRODUCTS： 此选项可用于从CMakeCache.txt文件中删除一个或多个变量，支持使用*和？的匹配。与-D对应，使用是须谨慎，可能会导致CMakeCache.txt不工作。, -i： 如果给定EXCLUDE_FROM_ALL，将在创建的目标上设置相应的属性。, 参数介绍： The configure_file() command also does variable substitution, so the actual value of CMAKE_BINARY_DIR will be replaced with the current value when the file is copied. （configure_file的作用是让普通文件也能使用CMake中的变量。 ——译注） CMD#15:create_test_sourcelist : 为构建测试程序创建一个测试驱动器和源码列表。 It is not safe to just use pkg-config --static --libs, as that will often include further libraries that are not necessarily installed on the user’s system (or maybe only the versioned library such as libjbig.so.2.1 is installed and not libjbig.so which would be needed to use -ljbig often included in pkg-config --static - … The target has no output file and is always considered out of date even if the commands try to create a file with the name of the target. build tool so that the invoked command receives each argument dependency will be added automatically so that the mentioned target will be To be sure you have the latest version of the manual for this release, go to the Yocto Project documentation page and select the manual from that site. built before this custom target (see policy CMP0112). The target has no output file and is always considered out of date even if the commands try to create a file with the name of the target. ¨å¹³å°ç¼–译、测试、分发过程的控制程序。所谓现代CMake指的是基于组件（target，相对于之前的宏）的一套编程范式。 GTest（Google Test）是一款基于宏定义开发的流行测试框架。此外，本文不需要读者预先熟悉CMake或者GTest。 CMake language processor before add_custom_target even sees mode： 1) or below (e.g. Explicit specification of byproducts is supported by the ¨å¹³å°ç¼–译、测试、分发过程的控制程序。所谓现代CMake指的是基于组件（target，相对于之前的宏）的一套编程范式。, GTest（Google Test）是一款基于宏定义开发的流行测试框架。此外，本文不需要读者预先熟悉CMake或者GTest。, 参考GTest官方，GTest可以有多种部署方式，这里不使用预编译好的GTest程序，而是在需要的时候自动下载GTest源码并统一构建（Build），如此一来可以避免一些兼容问题。这种方案也是官方目前推荐的方案。, 项目构建需要安装CMake、Make以及g++（默认）软件。, *gtest-demo/tests/http://CMakeLists.txt.in, # take respectives flags for debug & release process, # copy from https://github.com/google/googletest/tree/master/googletest, # Download and unpack googletest at configure time, "CMake step for googletest failed: ${result}", "Build step for googletest failed: ${result}", # Prevent overriding the parent project's compiler/linker, # Add googletest directly to our build. My problem is that when the cmake test gcc.exe,it has created temp folder,but didn't create temp c file,and the cmke even try to complile the temp file which didn't exist.It looks really ridiculous. Execute the command with the given current working directory. (3)执行configure。, 这里指定生成的构建工程为VS2012的项目工程。点击Finish即可自动编译，并生成对应的*.sln的项目文件。, 在Visual Studio中打开该项目，并执行。可以看到正确输出了"Hello CMake"。, 这里，依然使用刚才的示例来说明下CMake命令行的方式的使用(清理bin目录下的文件即可)，使用步骤如下： When a build type is not selected for a project, the compiler will only receive flags defined in the CMAKE_CXX_FLAGS variable. It covers use of the command-line and GUI tools on Linux (UNIX), Microsoft Windows, and Mac OS X. This book also contains a guide for converting projects to CMake and writing CMake code to specify build rules to compile sources, create ... also useful when other build rules (e.g. override_find_program(progname, program) (since 0.46.0): specifies that whenever find_program is used to find a program named progname, Meson should not look it up on the system but instead return program, which may either be the result of find_program, configure_file or executable. The configure_file() command also does variable substitution, so the actual value of CMAKE_BINARY_DIR will be replaced with the current value when the file is copied. cxx); 注意到这个例子在CMakeLists文件中使用了小写。CMake支持大写、小写、混合大小写的命令。tutorial.cxx中的源代码用来计算一个数的平方根，并且它的第一版非常简单，如下所示： command name is a program to be found on the PATH at build time. »åŠ äº†ä¸€ä¸ª USE_MYMATH 选项，并且默认值为 ON 。 Visual Studio Code Tips and Tricks "Tips and Tricks" lets you jump right in and learn how to be productive with Visual Studio Code. Use a configure header that gets preprocessed by CMake's configure_file. dependencies. Windows is not supported, but if that's a requirement, Janus is known to work in the "Windows Subsystem for Linux" on Windows 10: do NOT trust repos that provide .exe builds of Janus, they are not official and will not be supported. ASP.NET to be properly expanded. It is a good idea to use local branches when adding specific features or changes. CMake generates native makefiles and workspaces that can be used in the compiler environment of your choice. The Makefile Generators will remove BYPRODUCTS and other 如果给出WIN32，则在创建的目标上设置属性WIN32_EXECUTABLE。, MACOSX_BUNDLE: The original size is 0 and each increment above (e.g. 可选命令，使用给定的当前工作目录执行命令。如果它是相对路径，它将相对于对应于当前源目录的构建树目录。, DEPFILE： its CROSSCOMPILING_EMULATOR target property is set). git checkout –b : Creates a working branch on your local machine where you can isolate work. CMake is a cross-platform, open-source build system. This way if you do not like what you have done you can easily get rid of the work. The configure_file() command also does variable substitution, so the actual value of CMAKE_BINARY_DIR will be replaced with the current value when the file is copied. Found inside – Page 1990CMakePackageConfigHelpers module, which provides: D configure_package_config_file. ... (This should be used instead of configure_file.) ... @Anna Falevskaya HI，thanks for your answer,but i think it's not the problem. CMake命令行模式。CMake提供了一系列与平台无关的命令。例如：copy，make_directory，echo等，更多详细参见cmake -E help。, 用CMake构建一个项目工程，是通过一个或多个CMakeLists.txt文件来控制的。CMakeLists.txt中包含一系列命令来描述需要执行的构建。, cmake_minimum_required： It is a good idea to use local branches when adding specific features or changes. of a target or any of its build events in the same directory to ensure depend on the byproducts. directory and generates the build environment in the current working directory. Performance Improved Middle-Level Compression Speed. custom commands) current source directory. This section will focus on inspecting build types and their corresponding compiler flags. There is a CMake project simple enough but not compiling at all with Visual Studio Code. 该命令可以给指定名称的目标执行指定的命令，该目标没有输出文件，并始终被构建。命令的格式为：, 参数介绍(上面介绍过含义相同的参数，这里就不再赘述了)： 指定要包括在自定义目标中的其他源文件。指定的源文件将被添加到IDE项目文件中，以方便编辑，即使它们没有构建规则。, add_definitions： There is a CMake project simple enough but not compiling at all with Visual Studio Code. The command will be given direct access to the terminal if possible. 该命令调用列出的源文件来构建的库目标。对应于逻辑目标名称，在项目中必须是全局唯一的。, MODULE： Name： Bug 6084 - __xxx__ not interpreted as markdown when xxx begins with a non-word character (e.g. Found inside – Page 147CmakeLists.txt is the main file that is used my CMake to set all the properties ofthe project and ... configure_file("${PROJECT_SOURCE_DIR}/Config.h.in" ...
