Hi Steve
SET(VAR "C:\path\to\foo")
->”\p” and “\f” are interpreted as escape sequences
Setting VAR via CMake GUI it is internally interpreted as:
"C:\\path\\to\\foo"
That means you have to do following to obtain what you want to:
SET(INPUT_VAR "C:\\path\\to\\foo") #or just set this variable via the interface
message(STATUS ${INPUT_VAR})
string(REGEX REPLACE "\\\\" "\\\\\\\\" OUTPUT_VAR ${INPUT_VAR}) #each "\\" ==
"\"
message(STATUS ${OUTPUT_VAR})
C:\\path\\to\\foo
(internally again: C:\\\\path\\\\to\\\\foo)
Best,
SirAnn

Betreff: [CMake] string REGEX question
I have the following string in a variable "C:\path\to\foo"
I want to do something like the following:
string(REGEX REPLACE "\\" "\\\\" OUTPUT_VAR ${INPUT_VAR})
where INPUT_VAR contains the original string.
I want the result to be:
C:\\path\\to\\foo
I'm just not seeing how to make this regular expression work. If you have any
suggestions I would appreciate the help!
Thanks in advance,
Steve
