# The addon target of an addon repository: the root CMakeLists.txt of the
# repository includes cmake/config.cmake, calls project() and then this file, so
# the repository is a single CMake project that the driver of the entry script
# (fib-addon/scripts/build) configures and builds in one pass.
#
# The include below keeps the contract explicit: the build environment
# (BUILD_OS/BUILD_ARCH/BUILD_TYPE, DIST_DIRNAME and BT_BIN_DIR) has to be known
# before project() runs, and config.cmake reports a top-level project that
# called project() first.

# node-addon-api is a C++17 library: napi.h includes <string_view> and uses
# std::string_view unconditionally (MSVC compiles as C++14 by default, where
# <string_view> exists but std::string_view does not).  A repository that states
# an older standard is lifted here; an unset one keeps the default of
# build_tools (C++20).
