Comment (by ryandesign):

 cmake binaries link with curl:

 {{{
 $ otool -L /opt/local/bin/{ccmake,cmake,cpack,ctest}|egrep '^/|curl'
 /opt/local/bin/ccmake:
         /opt/local/lib/libcurl.4.dylib (compatibility version 12.0.0,
 current version 12.0.0)
 /opt/local/bin/cmake:
         /opt/local/lib/libcurl.4.dylib (compatibility version 12.0.0,
 current version 12.0.0)
 /opt/local/bin/cpack:
         /opt/local/lib/libcurl.4.dylib (compatibility version 12.0.0,
 current version 12.0.0)
 /opt/local/bin/ctest:
         /opt/local/lib/libcurl.4.dylib (compatibility version 12.0.0,
 current version 12.0.0)
 }}}

 So you can't ''just'' remove the dependency from `depends_lib`. You would
 also have to tell the build system not to link with MacPorts curl even if
 it is installed. But I don't know if that's the right thing to do.

 cmake was made to use MacPorts curl to resolve #43133, in which cmake was
 trying to fetch a file but couldn't, because previously cmake was using a
 bundled copy of curl which didn't support https. Certainly I agree with
 the general preference for using MacPorts libraries over potentially out-
 of-date bundled libraries.

 I don't know how important it is for cmake itself to be able to
 [https://cmake.org/cmake/help/latest/module/FetchContent.html fetch
 content]. In MacPorts ports of course we would prefer that that not
 happen, but users may also use MacPorts cmake for their own non-MacPorts
 projects, and they might expect this functionality to exist.

 Therefore it's probably best for cmake to continue to link with MacPorts
 curl and for a different resolution to the circular dependency to be
 found.
