Install Following tools:

• Visual Studio Community 2019 from visualstudio.microsoft.com/vs/ (Older versions are not supported as Orca Slicer requires support for C++17, and newer versions should also be ok);
• Cmake from cmake.org
• Git from gitforwindows.org
• Perl from strawberryperl

Suppose you download the codes into D:/work/Projects/BambuStudio
create a directory to store the dependence built: D:/work/Projects/OrcaSlicer_dep

cd BambuStudio/deps
mkdir build;cd build
cmake ../ -G "Visual Studio 16 2019" -DDESTDIR="D:/work/Projects/OrcaSlicer_dep" -DCMAKE_BUILD_TYPE=Release
msbuild /m ALL_BUILD.vcxproj

It takes "00:14:27.37" to finish it on my machine (11th Gen Intel(R) Core(TM) i9-11900 @2.50GHz 2.50 GHz, with 32.0 GB DDR)

create a directory to store the installed files at D:/work/Projects/BambuStudio/install_dir
cd BambuStudio
mkdir install_dir
mkdir build;cd build

set -DWIN10SDK_PATH to your windows sdk path(for example: C:/Program Files (x86)/Windows Kits/10/Include/10.0.19041.0) in below command:
cmake .. -G "Visual Studio 16 2019" -DBBL_RELEASE_TO_PUBLIC=1 -DCMAKE_PREFIX_PATH="D:/work/Projects/OrcaSlicer_dep/usr/local" -DCMAKE_INSTALL_PREFIX="../install_dir" -DCMAKE_BUILD_TYPE=Release -DWIN10SDK_PATH="C:/Program Files (x86)/Windows Kits/10/Include/10.0.19041.0"

then build it using command
cmake --build . --target install --config Release

or building it under the Visual Studio 2019
(set the OrcaSlicer_app_gui as start project)
