.SYNOPSIS
Creates NSIS "File" function calls required for Qt packaging.

.DESCRIPTION
This script creates an NSIS-compatible file based on the output of
windeployqt. If Qt is present, version 5.3 or later is required.
Otherwise a dummy file will be created.

If building with Qt, QMake must be in your PATH.

.PARAMETER Executable
The path to a Qt application. It will be examined for dependent DLLs.

.PARAMETER FilePath
Output filename.

.PARAMETER DebugConfig
Assume debug binaries.

.INPUTS
-Executable Path to the Qt application.
-FilePath Output NSIS file.

.OUTPUTS
List of NSIS commands required to package supporting DLLs.

.EXAMPLE
C:\PS> .\windeployqt-to-nsis.ps1 windeployqt.exe ..\..\staging\wireshark.exe qt-dll-manifest.nsh [-DebugConfig]
#>
