clion编写opencv, CmakeList的简单使用入门

说明

以下是opencv的demo程序需要配置的CmakeList.txt内容和main.cpp的内容
可以直接使用cmake编译，也可以通过clion使用cmake编译

# include_direcctory 和 link_directorys 必须在定义相关的target（add_executable or add_library)之前
# target不会到在他后面定义的directory中寻找.h文件和.lib文件，因此错序可能会报错
# 指定搜索.h file的目录
include_directories(${OPENCV}/include ${OPENCV}/include/opencv)     # include directory for all targets
# target_include_directories(target dir1 dir2 ...)                  # include directory for specified target

# 指定搜索.lib file的目录
link_directories(${OPENCV}/lib)   # libraray search path
# link_libarrays(lib1, lib2...)                         # link library to all targets

# 指定从哪些源代码文件中生成exe或lib
# add_library(target source1, source2...)                 # compiler sources to a library named target, not a exe
add_executable(opencv_adaboost ${SOURCE_FILES})         # compiler sources to a exe named target, not a library
target_link_libraries(opencv_adaboost ${OPENCV_LIB})    # link library to specified target. must after define target opencv_adaboost

    cvReleaseImage(&test);
