+\subsubsection*{Generate Visual Studio Projects with CMake}
+
+ORE 1.8.9 and later will be shipped without the Visual Studio project and solution files. The Visual Studio projects can be auto-generated from the CMake project files.
+
+\begin{enumerate}
+
+\item Download and install Visual Studio Community Edition (Version 2013 or later). 
+During the installation, make sure you install the Visual
+C++ support under the Programming Languages features (disabled by default).
+
+\item Download and install CMake for Windows (https://cmake.org/download/). Visual Studio Community Edition 2019 or later supports CMake and you can install the feature 'C++ CMake Tools for Windows' instead of installing CMake as standalone program.
+
+\item Set environment variables: \\
+	\begin{itemize}
+  	\item  {\tt \%BOOST\%} pointing to your directory, e.g, {\tt C:{\bs}boost\_1\_72\_0} 
+  	\item {\tt \%BOOST\_LIB32\%} pointing to your Win32 lib directory, e.g, {\tt C:{\bs}boost\_1\_72\_0{\bs}lib32\-msvc\-14.0} 
+	\item  {\tt \%BOOST\_LIB64\%} pointing to your x64 lib directory, e.g, {\tt C:{\bs}boost\_1\_72\_0{\bs}lib64\-msvc\-14.0} 
+     \end{itemize}
+
+\item Generate MSVC project files from CMake files:
+\begin{itemize}
+\item Open a Visual Studio Tools Command Prompt
+\begin{itemize}
+\item 32-bit: VS2022/x86 Native Tools Command Prompt for VS 2022
+\item 64-bit: VS2022/x64 Native Tools   Command Prompt for VS 2022
+\end{itemize}
+\item Navigate to the ORE root directory
+\item Run CMake command:
+\begin{itemize}
+\item 32-bit: \\
+{\tt cmake -G "Visual Studio 17 2022" -A x64 -DBOOST\_INCLUDEDIR=\%BOOST\% -DBOOST\_LIBRARYDIR=\%BOOST\_LIB64\% -DMSVC\_LINK\_DYNAMIC\_RUNTIME=true -B build}
+\item 64-bit: \\
+{\tt cmake -G "Visual Studio 17 2022" -A x32 -DBOOST\_INCLUDEDIR=\%BOOST\% -DBOOST\_LIBRARYDIR=\%BOOST\_LIB32\% -DMSVC\_LINK\_DYNAMIC\_RUNTIME=true -B build}
+\end{itemize}
+Replace the generator "Visual Studio 17 2022" with the actual installed version.
+The solution and project files will be generated in the {\tt $\langle$ORE\_ROOT$\rangle${\bs}build} subdirectory.
+\end{itemize}
+
+\item Open the {\tt build{\bs}ORE.sln} and build the entire solution (again, make sure to select the correct platform in the configuration manager first).
+\end{enumerate}

 \subsubsection*{Unix}
 
 With the 5th release we have discontinued automake support so that ORE can only be built with CMake on Unix systems, as follows.
