[CMake] CMake regexes: Case insensitive and whitespace matching

[Daniel Lueken]

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
