Summary

• Set PLUGIN_INSTALL_DIR as a CMake cache entry (CACHE PATH "Plugin install path") in CMakeLists.txt across all platform/precision branches so packagers (e.g., Homebrew) can override -DPLUGIN_INSTALL_DIR=... while preserving existing defaults.
• Document the PLUGIN_INSTALL_DIR CMake cache variable in README.md.

Background

PLUGIN_INSTALL_DIR was previously made a cache entry on macOS in #13 (33c7db3), but regressed to a non-cache variable when 76e5d49 (authored prior to #13) was rebased and merged in #10 (4cbd806).

Fixes #12

Summary by CodeRabbit

• New Features

  • The plugin installation directory can now be customized across supported platforms and build configurations.

• Documentation

  • Installation instructions explain how to set a custom plugin directory and include an example.

Walkthrough

CMake now exposes PLUGIN_INSTALL_DIR as a cache path across platform and precision branches. The README documents how to override it. Existing platform-specific default locations remain unchanged.

Changes: Plugin Install Path

Layer / File(s)	Summary
Configure and document the install path CMakeLists.txt, README.md	CMake declares PLUGIN_INSTALL_DIR as a cached PATH while retaining the existing defaults. The README explains how to set a custom path and includes an example.

Packagers can now override the plugin install directory with -DPLUGIN_INSTALL_DIR, as intended. One caveat: if you switch precision or install prefix in an existing build directory, the previously cached default can persist. Clear the cache or pass the path explicitly in that case. This is a bounded issue, so the change can merge with that awareness.

Full details: Title check

Explanation

The title "fix(cmake): set PLUGIN_INSTALL_DIR as a cache entry" names the main change. The PR defines PLUGIN_INSTALL_DIR as a CMake CACHE PATH entry in CMakeLists.txt across platform and precision branches, and the README documents the override. The title is specific, follows the conventional-commit style, and matches the stated objective of restoring cache entries lost in a rebase.

Full details: Linked Issues check

Explanation

Issue #12 requires a configurable PLUGIN_INSTALL_DIR. The reviewed CMakeLists.txt defines PLUGIN_INSTALL_DIR as CACHE PATH in the WASM, double-precision, and single-precision branches. The existing platform-specific defaults remain. CMake install targets use this variable. The supplied change summary also records documentation in README.md and a -DPLUGIN_INSTALL_DIR=... override example.

Full details: Out of Scope Changes check

Explanation

The supplied whole-PR summary limits the changes to CMakeLists.txt and README.md. The changes support Issue #12 by enabling and documenting the install-directory override. No unrelated change is shown.

Major · Functional Correctness · Quick win

Refresh the generated cache default when its inputs change.

CMake does not overwrite an existing CACHE entry on a later set(... CACHE ...) call unless FORCE is used. (cmake.org)

For example, configure with USE_DOUBLE=ON, then reconfigure the same build directory with -DUSE_DOUBLE=OFF. PLUGIN_INSTALL_DIR remains the plugins64 path, so the install rule uses the wrong precision directory. Changing CMAKE_INSTALL_PREFIX or USE_LIB64 has the same problem. Preserve explicit -DPLUGIN_INSTALL_DIR overrides, but update the cache when the generated default changes, or clearly require clearing the cache when changing these inputs.
