实际上他们两个可以达到一个目标（对于文件操作），但是又有本质上的区别，文档没有细看，但是一般利于项目的管理，使用install，install命令如果在cmake命令中没有指名install参数，实际上时不会执行的，只有在cmake命令中指名install，install命令（在CmakeLists.txt里）才会执行。

Demo:

cmake_minimum_required(VERSION 2.8)#set(CMAKE_C_COMPILER "D:\VS2008Release\VC\bin\amd64")
#set(CMAKE_CXX_COMPILER "D:\VS2008Release\VC\bin\amd64")PROJECT(VisualStaticMT) #set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/Lib)
#set(ARCHIVE_OUTPUT_DIRECTORY "${CMAKE_BINARY_DIR}/Lib")
#message(STATUS ${CMAKE_BINARY_DIR})set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)
