# 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:
# For the ?TBD? - Suggest trying GNU-based and adding the appropriate toolchain file.
# For Toolchain examples see _deps/cmake-src/toolchain/arm-none-eabil-gcc.toolchain.cmake
