Description

When compiling 32-bit Binaries on Windows, the output for example of dcmdump --version shows:

$dcmtk: dcmdump v3.6.5 2019-10-28 $

dcmdump: Dump DICOM file and data set

Host type: AMD64-Windows
Character encoding: CP1252
Code page: 850 (OEM) / 1252 (ANSI)

Note that AMD64 is shown as host type despite the binary being a 32-bit binary. This is confusing.
Apparently the CMake variable SYSTEM_PROCESSOR has the value "AMD64" when compiling for Windows, even though 32-bit binaries are generated.

An alternative could be to use the CMake variable CMAKE_GENERATOR_PLATFORM instead of SYSTEM_PROCESSOR when available.
On Visual Studio, this would have the value "Win32" for 32-bit builds and "x64" for 64-bit builds.
