2.3.1 使用string(REGEX MATCHALL)进行分割 在CMake中,我们可以使用string(REGEX MATCHALL)来进行字符串分割。这个命令会使用正则表达式来匹配字符串中的所有子串。 例如,我们可以这样使用string(REGEX MATCHALL): string(REGEX MATCHALL"[0-9]+"result"Hello123World456")message(${result}) 这段代码会输出123 4...

在这种情况下,你可能需要一个选项,逐步将事物分解成更独立的单元——可能要把它们放在单独的构建管道中,或者只是为了在一个更小的范围内工作,这可以被如 CLion 这样的 IDE 加载。 你可以通过在嵌套目录中的 listfile 添加 project() 命令来实现。只是不要忘记用 cmake_minimum_required() 它前缀。 由于支持项目...
file(STRINGSmyfile.txt myfile) 该命令在变量myfile中存储了一个list,该list中每个项是输入文件中的一行文本。 GLOB选项将会为所有匹配查询表达式的文件生成一个文件list,并将该list存储进变量variable里。文件名查询表达式与正则表达式类似,只不过更加简单。如果为一个表达式指定了RELATIVE标志,返回的结果将会是相对于...
