2.3.4 Installing OSI for C++ on Windows

Prerequisites

You have installed everything described in Section 2.3.1, "Installing protobuf for static / dynamic linking".

Steps

Open a terminal as administrator.

Clone the Open Simulation repository.

git clone https://github.com/OpenSimulationInterface/open-simulation-interface.git

Switch to the repository directory.
```
cd open-simulation-interface
```
Create a new directory for the build.
```
mkdir build
```
Switch to the new directory.
```
cd build
```

Run cmake. To build a 64-bit target, add Win64 to the generator name. In this case, protobuf and protoc.exe must be in 64-bit mode too.

cmake .. [-G <generator>] [-DCMAKE_INSTALL_PREFIX=<osi-install-directory>]

If you used vcpkg to install protobuf, then provide the target and toolchain file information, as follows

cmake .. -DVCPKG_TARGET_TRIPLET=x64-windows-static-md -DCMAKE_TOOLCHAIN_FILE=C:/path/to/vcpkg/scripts/buildsystems/vcpkg.cmake -A x64 [-G <generator>] [-DCMAKE_INSTALL_PREFIX=<osi-install-directory>]

Build and install OSI.

cmake --build . [--config Release]
cmake --build . --target install
