This PR sets PLUGIN_INSTALL_DIR as a cache entry instead of a hardcoded variable on macOS so that packaging plug-ins is possible using Homebrew (see issue #12).
This also fixes FindFLUIDSYNTH.cmake to use the correct variable name for FluidSynth libraries so FluidSynth opcodes can actually be built on macOS.
