Minimize configuration dependencies

Keep configuration dependencies minimal and platform-aware. Avoid including unnecessary configuration files or external tools that can introduce unpredictable behaviors or unrelated settings. For platform-specific code, use conditional compilation to ensure that components are only built and executed in relevant environments.

When working with build configurations:

1. Only include necessary configuration files that are directly relevant to the component being built
2. Use conditional compilation for platform-specific code
3. Minimize dependencies on external tools with behaviors that may change unexpectedly

Example of good practice for platform-specific code:

// For header files
#ifndef SRC_NODE_PLATFORM_FEATURE_H_
#define SRC_NODE_PLATFORM_FEATURE_H_

#ifdef _WIN32
// Windows-specific declarations
#endif

// Cross-platform declarations

#endif  // SRC_NODE_PLATFORM_FEATURE_H_

// For implementation files
#ifdef _WIN32
// Windows-specific implementation
#endif

Example of good configuration file practice:

// Only include what you need
'includes': ['toolchain.gypi'],  // Correct if only toolchain config is needed

// Avoid unnecessary inclusions
'includes': ['toolchain.gypi', 'features.gypi'],  // Incorrect if features.gypi adds unneeded complexity
