# Instructions
1. Set the environment variable `BUILDXL_BIN` to the BuildXL binary folder containing `bxl.exe`. For example, if your BuildXL repo is in `D:\BuildXL`, then building BuildXL itself using `bxl.cmd -Minimal` will put the `bxl.exe` in `D:\BuildXL\Out\Bin\debug\win-x64`.
1. Point the environment variable `BUILDXL_BIN` to the BuildXL binary folder path. For example, if you set up BuildXL in `D:\BuildXL` and built the repository, then `D:\BuildXL\Out\Bin\debug\win-x64` should be the value.
1. Run `.\build.ps1` from PowerShell, or equivalently `build.bat` from the command line prompt. This will:
    1. Generate the `build.ninja` specification by running `cmake -GNinja` in this directory. The next step depends on the `CMakeNinjaHelloWorld\build.ninja` file existing as the output of this invocation.
    1. Run the build with BuildXL using the Ninja resolver
1. Subsequent runs of this script should be fully cached. The Ninja-generation step (step 2) should be re-run if the CMake specifications change.

For further configuration options for the Ninja resolver, see [Resolvers](../../Public/Sdk/Public/Prelude/Prelude.Configuration.Resolvers.dsc).
Merged PR 770093: Add minimal documentation for the CMake/Ninja front-end and update examples Add minimal but self-contained documentation for using BuildXL with CMake and Ninja projects. Update the examples to reflect the recommended way to run CMake projects using Ninja generation, and marking the CMake resolver example as experimental and unsupported Related work items: #2125879 2024-03-07 00:04:27 +03:00			`# Instructions`
