Cmake的install與file命令的區別

實際上他們兩個可以達到一個目標（對於文件操作），但是又有本質上的區別，文檔沒有細看，但是一般利於項目的管理，使用install，install命令如果在cmake命令中沒有指名install參數，實際上時不會執行的，只有在cmake命令中指名install，install命令（在CmakeLists.txt里）才會執行。

 

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)
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
