if(<condition>)<commands>elseif(<condition>)# optional block,can be repeated<commands>else()# optional block<commands>endif() 在具体的条件判断流程中,若满足if() 指令中指定的<condition> 表达式,则执行第一部分的<commands>,如上例第2行部分,否则
CMake中的条件块是一个必须以if()开头并以endif()结尾的块状结构,在开头的if()和结尾的endif()之间可以添加任意数量的elseif(),但只能有单独一个的、可选的else(),其CMake条件块的结构命令如下: 1、if(<condition>)2、<commands>3、elseif(<condition>)#optionalblock,canberepeated4、<commands>5、else(...

复制 Rust中的if表达式需要使用大括号。 在Rust中,if表达式的值为最终被执行的块的值。因此,所有块都必须有相同的类型。例如,下面这个表达式不会被编译,因为一个错误的分号导致类型检查失败。 ifcond(){my_int(4)// Type is i32.}else{my_int(7);// Type is (), due to the ;} 复制 i32和()是不...
