#46739: cmake @3.0.2_1+universal: configuring PowerPC on an Intel system fails with
"Unknown option: --host=powerpc-apple-darwin10.8.0"

     Type:  defect    |     Status:  new
 Priority:  Normal    |  Milestone:
Component:  ports     |    Version:  2.3.3
 Keywords:            |       Port:  cmake
----------------------+-------------------
 The `muniversal-1.0` portgroup adds a “`--host`” option to
 `configure.args` when the host and build architectures differ. CMake’s
 configure script doesn’t recognize this option.
 {{{
 :debug:configure Executing command line:  cd
 "/opt/local/var/macports/build/_Users_larryv_Projects_MacPorts_git_trunk_dports_devel_cmake/cmake/work/cmake-3.0.2-ppc"
 && ./configure --prefix=/opt/local --mandir=/share/man
 --docdir=/share/doc/cmake --parallel=1
 --init=/opt/local/var/macports/build/_Users_larryv_Projects_MacPorts_git_trunk_dports_devel_cmake/cmake/work/cmake-3.0.2/macports.cmake
 --system-libs --host=powerpc-apple-darwin10.8.0
 :info:configure Unknown option: --host=powerpc-apple-darwin10.8.0
 }}}

 This only manifests on Snow Leopard because the `cmake` portfile already
 sets
 {{{
 supported_archs i386 x86_64
 }}}
 on Intel and
 {{{
 supported_archs ppc ppc64
 }}}
 on PowerPC.

 The [[attachment:cmake-no-host.patch|attached patch]] stops
 `muniversal-1.0` from adding the option and allows the build to complete
 successfully, but I don’t know whether it’s the cleanest solution. Another
 approach would be to drop PowerPC support entirely; I don’t know how
 useful it is to build `cmake` itself universally.
