自動化建構系統，CMake 3.4.0 發布

CMake 是一個跨平臺的自動化建構系統,它使用一個名為 CMakeLists.txt 的文件來描述構建過程,可以產生標準的構建文件,如 Unix 的 Makefile 或Windows Visual C++ 的 projects/workspaces 。文件 CMakeLists.txt 需要手工編寫,也可以通過編寫腳本進行半自動的生成。CMake 提供了比 autoconfig 更簡潔的語法。

CMake 3.4.0 發布，該版本增加新的測試操作器用于 if() 命令，主要更新內容如下：

* 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.
  
  棄用的特性
  
  
• 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. </p>
