CMake 3.4.0 发布，该版本增加新的测试操作器用于 if() 命令，主要更新内容如下： * The "if()" command learned a new "TEST" operator that evaluates to true if a given test name has been defined by the "add_test()" command. See policy "CMP0064". * The "install(DIRECTORY)" command "DESTINATION" option learned to support "generator expressions". * The "install(FILES)" command "DESTINATION" option learned to support "generator expressions". * CMake learned to honor "*.manifest" source files with MSVC tools. Manifest files named as sources of ".exe" and ".dll" targets will be merged with linker-generated manifests and embedded in the binary. 弃用的特性 * The "CMakeExpandImportedTargets" module is now documented as deprecated. See module documentation for an explanation. * The "CMAKE_USE_RELATIVE_PATHS" variable no longer has any effect. Previously it was partially implemented and unreliable. 更多内容请看：KitWare blog CMake 是一个跨平台的自动化建构系统,它使用一个名为 CMakeLists.txt 的文件来描述构建过程,可以产生标准的构建文件,如 Unix 的 Makefile 或Windows Visual C++ 的 projects/workspaces 。文件 CMakeLists.txt 需要手工编写,也可以通过编写脚本进行半自动的生成。CMake 提供了比 autoconfig 更简洁的语法。 CMake 3.4.0 发布，自动化建构系统下载地址
