# Overall Compile Options
# Note the compile option strategy is to error on everything and then
# Per library opt-out of things that are warnings/errors.
# This ensures that no matter what strategy for compilation you take, the
# builds will still occur.
#
# Only tested with GNU and Clang.
# Other options are https://cmake.org/cmake/help/latest/variable/CMAKE_LANG_COMPILER_ID.html#variable:CMAKE_%3CLANG%3E_COMPILER_ID
# Naming of compilers translation map:
#
# FreeRTOS | CMake
# -------------------
# CCS | ?TBD?
# GCC | GNU, Clang, *Clang Others?
# IAR | IAR
# Keil | ARMCC
# MSVC | MSVC # Note only for MinGW?
# Renesas | ?TBD?
