Hi,

Extended attribute support (--xattr) was omitted when curl was built with
cmake since cmake does not test for and set the HAVE_FSETXATTR defines.
I've attached a patch that addresses this issue.

The configure.ac, configure, make build system is not affected by this
issue.

I realize that cmake is the poorly maintained build option for curl,
however it is an option so it's worth fixing known issues.
