Building

Build requirements

• CMake
• Visual Studio 2017
• Windows PowerShell

Tested with Visual Studio 2017. Support for other compilers is unknown.

Starting the build

cso2-launcher uses CMake to generate project files and to build itself.

You can build it through CMake or generate its project files.

For example: to generate Visual Studio 2017 project files, open a terminal instance in the project's directory and run

# in powershell or in standard Windows cmd
cmake -G "Visual Studio 15 2017" ./

Or use the cmake-gui tool bundled with CMake for a more user friendly experience.

Once successfully generated, you can open CSO2Launcher.sln and build the project in your preferred configuration.

If built successfully, you will find the launcher inside out/bin/Win32/[your configuration].
