本文舉例的開源庫是opencv和gdal，其他塊源庫類似
使用本篇方法的前提是make install，即開源庫是install的。
當然，沒有install的也是可以用的，只需要在findpage前找到dir即可。
如找opencv：
set(opencv_dir /home/jie/third_party/opencv-3.4.0/build)
另外，findpage所返回的變數如opencv_libs有什麼可以去對應的findxx.cmake檔案中找。
opencv：
cmakelists：
# cmake needs this line
cmake_minimum_required(version 2.8)
# define project name
project(opencvtest)
# find opencv, you may need to set opencv_dir variable
# to the absolute path to the directory containing opencvconfig.cmake file
# via the command line or gui
find_package(opencv required)
# if the package has been found, several variables will
# be set, you can find the full list with descriptions
# in the opencvconfig.cmake file.
# print some message showing some of them
message(status "opencv library status:")
message(status " version: $")
message(status " libraries: $")
message(status " include path: $")
# add opencv headers location to your include paths
include_directories($)
# declare the executable target built from your sources
add_executable(main main.cpp)
target_link_libraries(main $)
cmakelist：
# cmake needs this line
cmake_minimum_required(version 2.8)
# define project name
project(gdaltest)
find_package(gdal required)
message(status "gdal library status:")
message(status " version: $")
message(status " libraries: $")
message(status " include path: $")
include_directories($)
add_executable(main test.cpp)
target_link_libraries(main $)

Cmake 構建程式
cmake 是乙個跨平台的自動化建構系統,它使用乙個名為 cmakelists.txt 的檔案來描述構建程式,可以產生標準的構建檔案,如 unix 的 makefile。cmakelists.txt 需要手工編寫,也可以通過編寫指令碼進行半自動的生成。cmake 提供了比 autoconfig 更簡...
