Hello Daniel, I tried it also in various ways, but I think the Regex in Cmake is very limited. What has worked for me was to use try_run and implement a simple c++ application which uses C++11's <regex> and accept one or two command line arguments (~ 15 lines of code).

尽可能多次地匹配正则表达式，并且将匹配的值用replacement expression 替换掉，然后存储到输出变量中。这个replace expression 可以引用包含匹配字符串的子表达式，这些匹配的字符串用圆括号隔开的\1，\2，…，\9等加以引用。

CMake has a regex string matching function STRING (REGEX MATCH ... ), but it does not work as normal regex should. Firstly, as quite a bit people already aware of, it does not recognize the beginning-of-string '^' and end-of-string '$'.

Hi all, In a number of standard CMake modules I encountered the following line: IF("${VARIABLE}" MATCHES "^${VARIABLE}$") Can anyone explain the rationale of this conditional to me.

This means that the regular expression ^ab+d$ matches abbd but not ababd, and the regular expression ^(ab|cd)$ matches ab but not abd. CMake language Escape Sequences such as \t, \r, , and \\ may be used to construct literal tabs, carriage returns, newlines, and backslashes (respectively) to pass in a regex. For example:
