Working Build System

[AOrthVector]

• 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.
• The project build system's internal dependency information needs to be accurate
• The project MUST be able to repeat the process of generating information from source files and get exactly the same bit-for-bit result. At the silver badge level, repeatable builds are only required for the project not external users
