[CMake] Escaping equal sign in custom command

[David Cole]

Try:


    cmake -D "DOXYGEN_TAGFILES:STRING=C:/bar/somevalue=C:/foo/another" -P configure_file.cmake


Because of the “:TYPE” parsing, “:” after the = sign can sometimes be misinterpreted by the regex code used to parse these out...



HTH,

David

Actually I did a bit more testing on this:

C:\Work\rdailey-hp\dpd-cmake\cmake\scripts\cmake>cmake -D
"DOXYGEN_TAGFILES=C:/bar/somevalue=C:/foo/another" -P configur
e_file.cmake
DOXYGEN_TAGFILES:

C:\Work\rdailey-hp\dpd-cmake\cmake\scripts\cmake>cmake -D
"DOXYGEN_TAGFILES=C/bar/somevalue=C:/foo/another" -P configure
_file.cmake
DOXYGEN_TAGFILES: C/bar/somevalue=C:/foo/another

The only difference in both cases is that I have removed the first
occurance of ":" (colon), which occurs after DOXYGEN_TAGFILES=. Why
would this cause the variable to not be defined??
