-- Downloading https://sourceforge.net/projects/gsoap2/files//gsoap-2.8/gsoap_2.8.111.zip/download... Failed. Status: 22;"HTTP response code said error"
CMake Warning at scripts/cmake/vcpkg_download_distfile.cmake:202 (message):
      
      Failed to download file.

The current archive gsoap_2.8.111.zip doesn't exist now. So update it to the latest version 2.8.112.

Note: No feature needs to test.

gsoap does not offer stable public downloads (they remove old versions from sourceforge), therefore we cannot include it in our testing set.

Instead, we should skip it and simply print a message for users:

message(FATAL_ERROR "gsoap does not offer permanent public downloads of its sources; all versions except the latest are removed from sourceforge. Therefore, vcpkg cannot support this library directly in the central catalog. If you would like to use gsoap, you can use this port as a starting point (${CMAKE_CURRENT_LIST_DIR}) and update it to use a permanent commercial copy or the latest public download. Do not report issues with this library to the vcpkg GitHub.")

(and add it as skip to ci.baseline.txt for all triplets).
