cxx_compiler_flags_overrides.cmake

# This file overrides the default compiler flags for CMake's built-in
# configurations (CMAKE_BUILD_TYPE). Most compiler flags should not be set here.
# The main purpose is to have very fine grained control of the compiler flags.

# We only override the defaults for Clang and GCC right now.
# CMake's MSVC logic is complicated so for now it's better to just inherit CMake's defaults.
