Fail the build if any errors are logged while it runs.
Without this flag, non-fatal errors, such as a failure to compile a shader for a particular platform, don't
cause the build to fail, but might result in incorrect behavior at runtime.
Always set this flag, unless errors are logged from packages or other third-party code that you can't fix, and you need the build to proceed despite them.
When this flag is set, errors logged from these build callbacks also fail the build:
IPreprocessBuildWithContext.OnPreprocessBuild,
IPostprocessBuildWithContext.OnPostprocessBuild,
IProcessSceneWithReport.OnProcessScene,
IPreprocessShaders.OnProcessShader, and
IPreprocessComputeShaders.OnProcessComputeShader.
This flag is the content directory equivalent of BuildOptions.StrictMode.
