Instructions

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.
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.
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.
2. Run the build with BuildXL using the Ninja resolver
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.
