 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.2.1
 Keywords:                |       Port:  cmake
--------------------------+-------------------
 I stumbled into an issue where cmake couldn't fetch a file using https due
 to missing SSL support in libcurl even if my curl from port had SSL
 support.

 It turns out that cmake is currently building builtin curl, expat zlib,
 bzip2 and libarchive. It should instead use port dependencies for ease of
 configuration.


 I'm also adding openmaintainer to the maintainers, if there's a specific
 reason why you would retain strict control over the port remember to
 remove it.

 Patch attached.
