<#

.SYNOPSIS
This script provides helpers for building msquic.

.PARAMETER Config
    The debug or release configuration to build for.

.PARAMETER Arch
    The CPU architecture to build for.

.PARAMETER Platform
    Specify which platform to build for.

.PARAMETER Static
    Specify a static library is preferred (shared is the default).

.PARAMETER Tls
    The TLS library to use.

.PARAMETER DisableLogs
    Disables log collection.

.PARAMETER LoggingType
    Set logging type

.PARAMETER SanitizeAddress
    Enables address sanitizer.

.PARAMETER CodeCheck
    Enables static code checkers.

.PARAMETER DisableTools
    Don't build the tools directory.

.PARAMETER DisableTest
    Don't build the test directory.

.PARAMETER DisablePerf
    Don't build the perf directory.

.PARAMETER Clean
    Deletes all previous build and configuration.

.PARAMETER InstallOutput
    Installs the build output to the current machine.

.PARAMETER Parallel
    Enables CMake to build in parallel, where possible.

.PARAMETER DynamicCRT
    Builds msquic with dynamic C runtime (Windows-only).

.PARAMETER StaticCRT
    Builds msquic with static C runtime (Windows-only).

.PARAMETER PGO
    Builds msquic with profile guided optimization support (Windows-only).

.PARAMETER UseXdp
    Enables XDP support (Linux-only).

.PARAMETER Generator
    Specifies a specific cmake generator (Only supported on unix)

.PARAMETER SkipPdbAltPath
    Skip setting PDBALTPATH into built binaries on Windows. Without this flag, the PDB must be in the same directory as the DLL or EXE.

.PARAMETER SkipSourceLink
    Skip generating sourcelink and inserting it into the PDB.

.PARAMETER Clang
    Build with Clang if available

.PARAMETER UpdateClog
    Build allowing clog to update the sidecar.

.PARAMETER ConfigureOnly
    Run configuration only.

.PARAMETER CI
    Build is occuring from CI

.PARAMETER OfficialRelease
    Build is for an official (tag) release.

.PARAMETER EnableTelemetryAsserts
    Enables telemetry asserts in release builds.

.PARAMETER UseSystemOpenSSLCrypto
    Use system provided OpenSSL libcrypto rather then statically linked. Only affects OpenSSL Linux builds

.PARAMETER EnableHighResolutionTimers
    Configures the system to use high resolution timers.

.PARAMETER ExtraArtifactDir
    Add an extra classifier to the artifact directory to allow publishing alternate builds of same base library

.PARAMETER LibraryName
    Renames the library to whatever is passed in

.PARAMETER SysRoot
    Directory with cross-compilation tools

.PARAMETER OneBranch
    Build is occuring from Onebranch pipeline.
