#318 add support for windows ARM64 in makensis.nsi

[Demon]

I was running test on Windows ARM64, and found that Example/makensis.nsi doesn't have ARM64 support yet.

The better way to do it is like this:

!macro InstallPlugin pi
  !if /FileExists ..\Plugins\amd64-unicode\${pi}.dll
    File "/oname=$InstDir\Plugins\amd64-unicode\${pi}.dll" ..\Plugins\amd64-unicode\${pi}.dll
  !endif
  !if /FileExists ..\Plugins\arm64-unicode\${pi}.dll
    File "/oname=$InstDir\Plugins\arm64-unicode\${pi}.dll" ..\Plugins\arm64-unicode\${pi}.dll
  !endif
  !if /FileExists ..\Plugins\x86-ansi\${pi}.dll
    File "/oname=$InstDir\Plugins\x86-ansi\${pi}.dll" ..\Plugins\x86-ansi\${pi}.dll
  !endif
  !if /FileExists ..\Plugins\x86-unicode\${pi}.dll
    File "/oname=$InstDir\Plugins\x86-unicode\${pi}.dll" ..\Plugins\x86-unicode\${pi}.dll
  !endif
!macroend

!macro InstallStub stub
  !if /FileExists ..\Stubs\${stub}-amd64-unicode
    File ..\Stubs\${stub}-amd64-unicode
  !endif
  !if /FileExists ..\Stubs\${stub}-arm64-unicode
    File ..\Stubs\${stub}-arm64-unicode
  !endif
  !if /FileExists ..\Stubs\${stub}-x86-ansi
    File ..\Stubs\${stub}-x86-ansi
  !endif
  !if /FileExists ..\Stubs\${stub}-x86-unicode
    File ..\Stubs\${stub}-x86-unicode
  !endif
!macroend

The nsi script, as far as I know, doesn't have a way to detect arm64 at compile time. Arm64 support still isn't complete yet. Maybe we could add a predefine to makensis / .nsi script that says what architecture it's targeting?

Yes, you can check it at runtime but not at compile time currently.

!include x64.nsh

${If} ${IsNativeARM64}

${EndIf}
