cmake拷贝文件夹的方法

cmake拷贝文件夹

• 使用add_custom_target完成拷贝
• 下面的核心代码， 以VS2015为例，将会创建一个名为copy_files的项目，见下图：
  

核心代码范例

# 拷贝文件夹到指定的目录
add_custom_target(copy_files ALL  
  VERBATIM 
  # COMMAND_EXPAND_LISTS 
  COMMAND ${CMAKE_COMMAND} -E make_directory "${publih_lib_include}" 
  COMMAND ${CMAKE_COMMAND} -E 
                  copy_directory  
                  "${CMAKE_CURRENT_SOURCE_DIR}/include" 
                  "${publih_lib_include}" 
) 

• copy_files是创建的项目名称，可任意修改
• publih_lib_include为自定义输出目录

代码解释

COMMAND ${CMAKE_COMMAND} -E make_directory "${publih_lib_include}" 

• 创建${publih_lib_include}宏所在目录

  COMMAND ${CMAKE_COMMAND} -E 
                  copy_directory  
                  "${CMAKE_CURRENT_SOURCE_DIR}/include" 
                  "${publih_lib_include}" 

• 将"${CMAKE_CURRENT_SOURCE_DIR}/include"文件夹拷贝到"${publih_lib_include}"
