# IREE has multiple facilities for building with out of tree plugin sources.
# The entry-point is via the -DIREE_CMAKE_PLUGIN_PATHS=<dir1;dir2> setting.
# Each directory in this list can have any of the following files in it, which
# will be included at the appropriate point in the CMake build:
#
# iree_compiler_plugin.cmake : Included in the context of the compiler/
# directory before sources and bindings. Will execute with source and
# binary dir ${IREE_BUILD_DIR}/compiler/plugins (shared with all other
# dirs).
# iree_runtime_plugin.cmake : Included in the context of the runtime/
# directory before sources. Will execute with source and binary dir
# ${IREE_BUILD_DIR}/runtime/plugins (shared with all other dirs).
#
# Typically, these plugins will perform additional project setup, and
# eventually call registration functions to advertise additional capabilities
# to the build system.
#
# Super-projects can populate the list IREE_CMAKE_BUILTIN_PLUGIN_PATHS to
# statically configure more plugin directories to be used.
#
# Compiler Plugins
# ----------------
# Compiler plugins are advertised to the build system via the function
# iree_compiler_register_plugin(), which associated a plugin id to a build target
# and registration function. See samples/compiler_plugins for examples.
#
# External HAL Driver Plugins
# ---------------------------
# HAL driver implementations are advertised to the build system via
# iree_register_external_hal_driver(), which specifies the name, target,
# registration function and optional source/binary directory.
