Building digikam on Windows

Hi folks,

Where can I find documentation on how to build Digikam for Windows?

What are the prerequisites?
I already installed Qt6 and Visual Studio Community Edition, but
bootstrap.vcpkg fails with:

CMake Error: CMake was unable to find a build program corresponding to
"NMake Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to
select a different build tool.
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage

I think the problem is b/c the VCPKG_DIR is wrong
VCPKG_DIR="/c/vcpkg"
I changed it to
VCPKG_DIR="/c/Program\ Files/Microsoft\ Visual\
Studio/2022/Community/VC/vcpkg"
but now CMake complains:
CMake Warning:
  Ignoring extra path from command line:
   "Studio/2022/Community/VC/vcpkg/scripts/buildsystems/vcpkg.cmake"

So it seems it cannot handle the folder names containing spaces.

Any idea how to workaround this?

I also tried creating a Windows batch file (bootstrap.vcpkg.bat) to avoid
Windows vs. Unix filename mess, but it did not work either (CMake failed to
compile a simple program).

Any help would be highly appreciated.
