Locating your KSP Install

KSPBuildTools needs to know where you have KSP installed in order to reference the game dlls. These are all specific to your own computer, and should not be included in your git repo.

There are several options for this. KSPBuildTools will choose in the following order. Either autodiscovery in the solution directory or setting a reference path in a .user file are the recommended methods for most users.

KSPBT_GameRoot MSBuild Property

If the KSPBT_GameRoot MSBuild property is already set, KSPBuildTools will use it as-is. This can be set in your .csproj.user file.

Environment Variable

Set the KSP_ROOT environment variable to the root of a KSP install. This is useful for CI workflows such as those using the compile action.

Solution Directory

KSPBuildTools will look for a “KSP” directory in your solution directory and use it if it is a valid install. It identifies valid installs by looking for assembly-csharp.dll in the appropriate subdirectory for your operating system.

Reference Path

KSPBuildTools will use the ReferencePath MSBuild property if it is a valid KSP install. This can be set in a user file located at {csproj path}.user. If you use Visual Studio, it can generate this file and property for you.

From Steam

KSPBuildTools will use the default Steam install location if it is a valid install
