:: VavCore Texture Binding Test Build Script
:: ================================================================================================
:: Purpose: Build VavCore texture binding test for Android
:: Author:  Generated with Claude Code
::
:: Prerequisites:
::   1. Android NDK r25+ installed
::   2. CMake installed and in PATH
::   3. VavCore library pre-built in ../../vavcore/lib/android-arm64-v8a/
::   4. Dependencies pre-built in project root lib/ directory
::
:: Usage:
::   1. Set Android NDK environment variable:
::      set ANDROID_NDK_HOME=C:\Android\android-ndk-r25c
::   2. Run this script:
::      build_test.bat        (for ARM64)
::      build_test.bat arm32  (for ARM32)
