list

参考文章：Cmake命令之list介绍

    list(LENGTH <list><output variable>)
    list(GET <list> <elementindex> [<element index> ...]<output variable>)
    list(APPEND <list><element> [<element> ...])
    list(FIND <list> <value><output variable>)
    list(INSERT <list><element_index> <element> [<element> ...])
    list(REMOVE_ITEM <list> <value>[<value> ...])
    list(REMOVE_AT <list><index> [<index> ...])
    list(REMOVE_DUPLICATES <list>)
    list(REVERSE <list>)
    list(SORT <list>)

为list添加一个元素

# 为list添加一个元素
list(APPEND CMAKE_PREFIX_PATH ${Qt5_DIR})
# 为list添加多个元素
set(CMAKE_MODULE_PATH ${CMAKE_SOURCE_DIR}/cmake/modules
                      ${CMAKE_MODULE_PATH})

遍历

FOREACH(one_dir ${SRC_LIST})                                    #遍历
    MESSAGE(${one_dir})                                                    #打印
ENDFOREACH(onedir)
