创建一个环境变量,使用set(ENV{<variable>} <value>) 指令用以声明,使用unset(ENV{<variable>})来清除某一个环境变量,其中ENV表示环境变量标志性前缀,variable指变量名称,value则为变量值,需要注意的是设定或读取环境变量时,都通过ENV前缀来访问环境变量,读取环境变量值时,要在ENV前加$符号;但if判断是否定义时,...
条件控制流if ```cmake some_command will be called if the variable's value is not: empty, 0, N, NO, OFF, FALSE, NOTFOUND, or -NOTFOUND. if(var) some_command(...) endif(var) ``` 循环结构:foreach和while ```cmake set(VAR a b c) ...

If set, CPM will forward all calls to CPMFindPackage as CPMAddPackage. This is useful to create reproducible builds or to determine if the source parameters have all been set correctly. This can also be set as an environmental variable. This can be controlled on a per package basis with ...
, YES, TRUE, Y, or a non-zero number. False if the constant is 0, OFF, NO, FALSE, N, IGNORE, NOTFOUND, the empty string, or ends in the suffix -NOTFOUND. Named boolean constants are case-insensitive. If the argument is not one of these constants, it is treated as a variable....
