.DESCRIPTION
Build tool using CMake, trying to properly setup the environment around compiler

.PARAMETER DisableInteractive
Disable script interactivity (useful for CI runs)

.PARAMETER BuildDebug
Build using the debug toolchain

.PARAMETER DisableDLLcopy
Disable automatic DLL deployment through vcpkg at the end

.PARAMETER EnableCUDA
Enable CUDA feature

.PARAMETER EnableCUDNN
Enable CUDNN feature

.PARAMETER EnableOPENCV
Enable OpenCV feature

.PARAMETER ForceOpenCVVersion
Force a specific OpenCV version

.PARAMETER EnableOPENCV_CUDA
Use a CUDA-enabled OpenCV build

.PARAMETER UseVCPKG
Use vcpkg to build tool dependencies. Clone it if not already found on system

.PARAMETER ForceLocalVCPKG
Use a copy of vcpkg in a subfolder of the tool folder, even if there might be another copy already provided by the system

.PARAMETER InstallDARKNETthroughVCPKG
Use VCPKG to install darknet thanks to the port integrated in it

.PARAMETER InstallDARKNETdependenciesThroughVCPKGManifest
Use VCPKG to install darknet dependencies using vcpkg manifest feature

.PARAMETER ForceVCPKGDarknetHEAD
Install darknet from vcpkg and force it to HEAD version, not latest port release

.PARAMETER DoNotUpdateVCPKG
Do not update vcpkg before running the build (valid only if vcpkg is cloned by this script or the version found on the system is git-enabled)

.PARAMETER VCPKGSuffix
Specify a suffix to the vcpkg local folder for searching, useful to point to a custom version

.PARAMETER VCPKGFork
Specify a fork username to point to a custom version of vcpkg (ex: -VCPKGFork "custom" to point to github.com/custom/vcpkg)

.PARAMETER VCPKGBranch
Specify a branch to checkout in the vcpkg folder, useful to point to a custom version especially for forked vcpkg versions

.PARAMETER DoNotUpdateTOOL
Do not update the tool before running the build (valid only if tool is git-enabled)

.PARAMETER DoNotDeleteBuildFolder
Do not delete temporary cmake build folder at the end of the script

.PARAMETER DoNotSetupVS
Do not setup VisualStudio environment using the vcvars script

.PARAMETER DoNotUseNinja
Do not use Ninja for build

.PARAMETER ForceCPP
Force building darknet using C++ compiler also for plain C code

.PARAMETER ForceStaticLib
Create library as static instead of the default linking mode of your system

.PARAMETER ForceVCPKGCacheRemoval
Force clean up of the local vcpkg binary cache before building

.PARAMETER ForceVCPKGBuildtreesRemoval
Force clean up of vcpkg buildtrees temp folder at the end of the script

.PARAMETER ForceVCPKGBuildtreesPath
Force using a different buildtrees dir for vcpkg

.PARAMETER ForceVCPKGPackagesRemoval
Force clean up of vcpkg packages folder at the end of the script

.PARAMETER CloneVCPKGShallow
Clone vcpkg as shallow repository

.PARAMETER ForceDisableVCPKGShallow
Force vcpkg clone to NOT be a shallow one

.PARAMETER ForceSetupVS
Forces Visual Studio setup, also on systems on which it would not have been enabled automatically

.PARAMETER ForceCMakeFromVS
Forces usage of CMake from Visual Studio instead of the system-wide/user installed one

.PARAMETER ForceNinjaFromVS
Forces usage of Ninja from Visual Studio instead of the system-wide/user installed one

.PARAMETER EnableCSharpWrapper
Enables building C# darknet wrapper

.PARAMETER DownloadWeights
Download pre-trained weight files

.PARAMETER Use32bitTriplet
Use 32 bit triplet for target build (windows-only)

.PARAMETER BuildInstaller
Build an installer using CPack

.PARAMETER ForceGCCVersion
Force a specific GCC version

.PARAMETER NumberOfBuildWorkers
Forces a specific number of threads for parallel building

.PARAMETER AdditionalBuildSetup
Additional setup parameters to manually pass to CMake

.EXAMPLE
./build -DisableInteractive -DoNotDeleteBuildFolder -UseVCPKG
