If I use the curl -L options you use I can see: GET /sources/glib/2.32/glib-2.32.1.tar.xz HTTP/1.1 Location: https://download.gnome.org/sources/glib/2.32/glib-2.32.1.tar.xz Issue another request to this URL: 'https://download.gnome.org/sources/glib/2.32/glib-2.32.1.tar.xz GET /sources/glib/2.32/glib-2.32.1.tar.xz Location: http://ftp.gnome.org/pub/GNOME/sources/glib/2.32/glib-2.32.1.tar.xz Issue another request to this URL: 'http://ftp.gnome.org/pub/GNOME/sources/glib/2.32/glib-2.32.1.tar.xz GET /pub/GNOME/sources/glib/2.32/glib-2.32.1.tar.xz ... then it seems that the initial http URL is redirected to https which is redirected to ftp... then I tried my CMake build with with your: file(DOWNLOAD "http://download.gnome.org/sources/glib/2.32/glib-2.32.1.tar.xz"; "/tmp/cmake_downloaded_glib-2.32.1.tar.xz" SHOW_PROGRESS STATUS status) message(STATUS "Download status = ${status}") and it works as expected. so my best bet is that the CMake command your are using has no SSL support which makes the "https" handling fail with "unsupported protocol". -- Erk L'élection n'est pas la démocratie -- http://www.le-message.org -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
