 Scripts to install compiled digiKam dependencies with MSVC under Windows
 ========================================================================
 
 * RESUME
 
     These scripts build a binary digiKam installer for Windows under Windows using VCPKG, MSVC tool-chain,
     and NSIS application.
 
     These scripts follow instructions from Qt bundle deployment for Windows as shared libraries
     available at this url: https://doc.qt.io/qt-6/windows-deployment.html
 
 * AUTHORS

 * DESCRIPTION
 
     These files and scripts are used to make binary installer of the digiKam
     Software Collection for Windows 64 bits. In addition to this README,
     there are comments in the scripts that provide some additional explanations for
     how they work.
 
 * BUNDLE CONTENTS
 
     Note: the bundle is relocatable and compatible with Windows 10 and later.

 * BUILD
 
     You must set the digiKam git tags to checkout right source code in installer.
     You must set the option to host debug symbols or not in installer.
 
     Note: Look in config.sh file for settings details.
 
     There are 4 scripts to be run by the user. 2 first ones installs
     VCPKG and all dependencies, next one digiKam, and last one makes a
     binary installer for Windows.
 
     To start compilation use these scripts in a Git-bash terminal:
 
     1) ./01-build-vcpkg.sh
 
     To build and install the base of VCPKG tools-chain including Qt framework and all low level dependencies.
 
     NOTE: due to long path problems while compiling under Windows and MSVC, VCPKG working directories must adjusted as shortest as possible:
         VCPKG_DIR=C:/vcpkg/
         INSTALL_DIR=E:/dk/
         DOWNLOAD_DIR=E:/d/
         BUILDING_DIR=E:/b/
 
         See the config.sh for details. Directories will be created automatically.
 
     2) ./02-build-extralibs.sh
 
     To Build and install the KDE framework components.
 
     3) ./03-build-digikam.sh
 
     To build and install digiKam and 3rd party plugins.
 
     4) ./04-build-installer.sh
 
     To build the Windows installer. Once you've successfully built digiKam, files to bundle may contain over 4GB of files.
     This script grabs the ~300MB needed to run digiKam and Showfoto.
     These include applications translations.
 
     This script creates Windows application links for the programs that will
     be run by the user (digiKam and Showfoto). It use makensis CLI tool from NSIS
     application dedicated to build Windows installer.
     The version >= 3 is required to be compatible with Windows 10.
 
     Depending of configuration done in config.sh, this script is able to upload automatically
     the bundle file on files.kde.org digiKam area through ssh. A valid ssh key configured
     with remote KDE server need to be set previously with the account. You can load ssh key
     at startup following instruction give at this url:
 
     https://unix.stackexchange.com/questions/90853/how-can-i-run-ssh-add-automatically-without-password-prompt
 
     Note: the bundle can be signed with GPG. You must setup your private and public keys before
     and put your passphare to a text file (~/.gnupg/dkorg-gpg-pwd.txt)
 
 * EXTRA SCRIPTS
 
     makeall.sh
 
     This script allows to build whole 64 bits installers from scratch.
 
     update.sh
 
     This script re-build only digiKam and installers 64 bits.
 
 * SSH CONFIGURATION
 
     Git-bash include openssh for windows which needs some tune to work properly with the remote KDE servers:
 
     - To register the git credential with your RSA key stored in C:/Users/${USER}/.ssh,
       create a C:/Users/${USER}/.bash_profile with this code:
 
     ```
     eval `ssh-agent`
 
     added_keys=`ssh-add -l`
     echo "Registered ssh keys: $added_keys"
 
     if [ ! $(echo $added_keys | grep -o -e "$HOME/.ssh/id_rsa") ] ; then
         ssh-add "$HOME/.ssh/id_rsa" &
     fi
     ```
     Git password will be ask once when the git-bash terminal session will be open.
 
     - To prevent unexpected disconnections from the remote server,
       create a C:/Users/{USER}/.ssh/ssh_config with this settings:
 
     ```
     Host *
     ServerAliveInterval 20
     TCPKeepAlive no
     ```
