additionalSOLibSearchPath does not work for remote debugging

まず、launch.json に記載されている Windows-to-Linux のリモート SSH デバッグシナリオを再現し、additionalSOLibSearchPath と、文書化されている LD_LIBRARY_PATH の回避策を比較します。additionalSOLibSearchPath のみを構成した場合に、リモート実行ファイルが共有ライブラリを読み込み、デバッグが成功すれば完了です。

Bug type: Debugger

Description
additionalSOLibSearchPath is not respected in debuging session using remote debugger from windows to linux using ssh.

According to maintainer in vscode-remote-release the issue is in debugger, not in the remote extension, see https://github.com/microsoft/vscode-remote-release/issues/5748

Work around
is to use "environment": [{ "name": "LD_LIBRARY_PATH", "value": "/path_to_libImportantLib/" },

To Reproduce

1. Compile an executable (exe_to_debug) on remote linux which depends on dynamic libraries in some path, eg /path_to_libImportantLib/ where libraries are found eg. libImportantLib.so
2. Debug executable on remote linux with dynamic libraries but without setting additionalSOLibSearchPath
   --> gdb fails as expected, output in gdb terminal
   exe_to_debug: error while loading shared libraries: libImportantLib.so: cannot open shared object file: No such file or directory
3. In Launch.json set
   "additionalSOLibSearchPath": "/path_to_libImportantLib/"
   Expected: Successful debugging
   Current Result: Same error as (2)
   `exe_to_debug: error while loading shared libraries: libImportantLib.so: cannot open shared object file: No such file or directory

Workaround:
Debugging works if I add following to Launch.json:

  "environment": [
    {
      "name": "LD_LIBRARY_PATH",
      "value": "/path_to_libImportantLib/"
    },
