#
# This script easy to build win32, linux, winuwp, ios, tvos, osx, android depends on $AX_ROOT/tools/ci/build1k.ps1
# usage: pwsh build.ps1 -p <targetPlatform> -a <arch>
# options
#  -p: build target platform: win32,winuwp,linux,android,osx,ios,tvos,watchos
#      for android: will search ndk in sdk_root which is specified by env:ANDROID_HOME first, 
#      if not found, by default will install ndk-r16b or can be specified by option: -cc 'ndk-r23c'
#  -a: build arch: x86,x64,armv7,arm64; for android can be list by ';', i.e: 'arm64;x64'
#  -cc: toolchain: for win32 you can specific -cc clang to use llvm-clang, please install llvm-clang from https://github.com/llvm/llvm-project/releases
#  -xc: additional cmake options: i.e.  -xc '-Dbuild','-DCMAKE_BUILD_TYPE=Release'
#  -xb: additional cross build options: i.e. -xb '--config','Release'
# examples:
#   - win32: 
#     - pwsh build.ps1 -p win32
#     - pwsh build.ps1 -p win32 -cc clang
#   - winuwp: pwsh build.ps1 -p winuwp
#   - linux: pwsh build.ps1 -p linux
#   - android: 
#     - pwsh build.ps1 -p android -a arm64
#     - pwsh build.ps1 -p android -a 'arm64;x64'
#   - osx: 
#     - pwsh build.ps1 -p osx -a x64
#     - pwsh build.ps1 -p osx -a arm64
#   - ios: pwsh build.ps1 -p ios -a x64
#   - tvos: pwsh build.ps1 -p tvos -a x64
# build.ps1 without any arguments:
# - pwsh build.ps1
#   on windows: target platform is win32, arch=x64
#   on linux: target platform is linux, arch=x64
#   on macos: target platform is osx, arch=x64
