Silver criterion build_standard_variables (MUST; group Quality, Working build system). Criterion text: Build systems for native binaries MUST honor the relevant compiler and linker (environment) variables passed in to them (e.g., CC, CFLAGS, CXX, CXXFLAGS, and LDFLAGS) and pass them to compiler and linker invocations. A build system MAY extend them with additional flags; it MUST NOT simply replace provided values with its own. If no native binaries are being generated, select "not applicable" (N/A).
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
