##################
# FLAGS for Extension for Locally Sourced Bundles
##################
# Use CMake options for user-configurable flags, and set default values.
# This makes it easier for users to enable/disable extensions via CMake-GUI or -D
# For flags that are always active by default in Makefile, set them ON here.

# Initializing EXT_FLAGS list
set(EXT_FLAGS "")

# Ensure these options are set in the main CMakeLists.txt or here.
# For now, we'll mimic the Makefile by directly setting the flags.
# In CMake, it's better to use `add_definitions` or `target_compile_definitions`
# directly rather than accumulating a string `EXT_FLAGS`.
# However, to strictly mimic, we'll collect the flags here.

# As per your build-list.mk, BPQ_EXT and IMC_EXT are enabled by default.
# ENABLE_IMC (added in ION 4.2.0): gates the IMC handler table in bpextensions.c
# and the IMC forwarding path in libbpP.c. It replaced the unconditional IMC
# inclusion of 4.1.x; without it the IMC block handlers are compiled but never
# registered, silently disabling multicast. IMC_EXT still gates the auto-attach
# extensionSpecs entry, so both are set.
# If you wish to make them configurable by the user, you'd use `option()` in CMakeLists.txt
# and check if they are ON.
# For direct translation, we'll append to EXT_FLAGS string.
# Note: In CMake, it's often better to use `add_definitions(-DBPQ_EXT)` directly
# in the main CMakeLists.txt where compilation flags are applied.
# This `EXT_FLAGS` variable here would then only serve as documentation or for
# a very specific concatenation logic.
# For the purpose of *this* build-list.cmake, we'll define it as a string
# that *could* be passed to add_definitions later.
set(EXT_FLAGS "-DBPQ_EXT -DIMC_EXT -DENABLE_IMC") # Matches your Makefile: EXT_FLAGS += -DBPQ_EXT -DIMC_EXT -DENABLE_IMC
