# ============================================================================
#  Ambivalence - build + install (macOS / Linux)
#
#  Usage:
#    make               clean Release build (VST3 + standalone) into build/<platform>
#    make install       remove stale installs, install built artifacts
#    make uninstall     remove installed artifacts
#    make clean         delete the build directory
#    make version       print the current git branch + commit
#    make info          print the resolved configuration
#
#  Notes:
#    - `make install` copies whatever is currently in build/<platform>, it does
#      not build. Run `make` first if you want a fresh build.
#    - JUCE is auto-fetched into ./build/JUCE on first build (shallow clone of
#      the JUCE_VERSION tag). Override with: make JUCE_PATH=/path/to/JUCE
#    - Install targets (user-level, no sudo required):
#        macOS:  VST3:       ~/Library/Audio/Plug-Ins/VST3/Ambivalence.vst3
#                Standalone: ~/Applications/Ambivalence.app
#        Linux:  VST3:       ~/.local/lib/vst3/Ambivalence.vst3
#                Standalone: ~/.local/bin/Ambivalence
