#!/usr/bin/env bash
# Linux 用ビルドスクリプト（VST3 / LV2 / CLAP / Standalone）
# 動作確認: WSL2 Ubuntu 24.04 + JUCE 8.0.12
#
# 使い方:
#   bash build_linux.sh             # Release ビルド + zip パッケージ生成
#   bash build_linux.sh Debug       # Debug ビルド（zip は生成しない）
#   BUILD_DIR=build-linux-dbg bash build_linux.sh Debug
#
# 必要パッケージ:
#   build-essential pkg-config cmake ninja-build git
