以前在cmake中要判断一个编译器是否支持C++11挺麻烦的,要根据编译器的类型和版本来判断。 从cmake 3.1版本开始增加了一个CMAKE_CXX_COMPILE_FEATURES变量用于获取当前C++ 编译器支持的编译特性列表,列表中是一些定义在CMAKE_CXX_KNOWN_FEATURES(C++已知特性)中的特性名字,比如cxx_lambdas即为当前编译器支持lambda表达式。
在cmake脚本中,设置编译选项可以通过add_compile_options命令,也可以通过set命令修改CMAKE_CXX_FLAGS或CMAKE_C_FLAGS。 使用这两种方式在有的情况下效果是一样的,但请注意它们还是有区别的: add_compile_options命令添加的编译选项是针对所有编译器的(包括c和c++编译器),而set命令设置CMAKE_C_FLAGS或CMAKE_CXX_F...

Apriori是Agarwal和Srikant在1994年首次提出的一种关联规则挖掘算法，它可以在特定类型的数据中找到关系，并将其表示为规则。关联规则挖掘最常用于营销，特别是在购物车的上下文中。这个应用领域被正式称为“购物车分析”。
