Thanks!

I’ll take away the message that it is indeed not possible and I didn’t miss anything there. ☺

Regards
Daniel

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).

Hope it helps

Regards Roman

Hi!

Is there any way to do case insensitive matching in string(REGEX … ?
Also, is there a way to match whitespaces?

What I would like to do, speaking in Perl-like syntax, is something like

string(REGEX REPLACE “/something\s+/stuff/i” …

Not knowing how to do this, I am currently doing something along the lines of

string(REGEX REPLACE “[Ss][Oo][Mm][Ee][Tt][Hh][Ii][Nn][Gg][\\r\\n\\t ]+” …

which looks pretty wrong to me. Converting everything to upper or lower case is also not an option since parts of the input string in which I need to replace something are case sensitive.

Best regards
Daniel Lueken
