使用CMAKE将字符串拆分为列表的常见方法是什么？ [英] What is common way to split string into list with CMAKE?

问题描述

假设我有以下字符串：

set(SEXY_STRING "I love CMake")

then I want to obtain SEXY_LIST from SEXY_STRING so I can do

list(LENGTH SEXY_LIST len)

和 len 等于3。

我在网上找到了几个宏，但我真的想知道如何以自然的方式做。

I've found several macros on web, but I really want to know how to do it in "natural" way. This operation seems to be very basic and widely used.

推荐答案

使用; 。我没有看到任何其他方式。

Replace your separator by a ;. I don't see any other way to do it.

cmake_minimum_required(VERSION 2.8)

set(SEXY_STRING "I love CMake")
string(REPLACE " " ";" SEXY_LIST ${SEXY_STRING})

message(STATUS "string = ${SEXY_STRING}")
# string = I love CMake

message(STATUS "list = ${SEXY_LIST}")
# list = I;love;CMake

list(LENGTH SEXY_LIST len)
message(STATUS "len = ${len}")
# len = 3
