为什么提交这份PR (why to submit this PR)

scons --target 的 target 意思给人很迷惑，一般用户都会理解为最终生成的target,而不是生成其他ide工程

你的解决方案是什么 (what is your solution)

添加 scons --ide 作为 --target 的别名，同时还保留原来的--target，ide这个名字意义大家一看就明白。

请提供验证的bsp和config (provide the config and bsp)

cmake不属于ide

so, 怎么办？似乎target这个名称也还好？

[mysterywolf]

改成--project-type吧，和上面的project-name一脉相承，用--而不是-

PR的意图我完全支持，改个命令名字就行
