MQL5 X-Drive CLI Compilation

Compile MQL5 indicators/scripts via command line using X: drive mapping to avoid "Program Files" path spaces that cause silent compilation failures.

When to Use (Proactive Triggers)

ALWAYS use this skill after:

• Editing any .mq5 file (indicator, script, EA)
• Editing any .mqh file (library/include)
• User says "compile", "build", "test it", "try it", "run it"
• User asks to verify changes work
• Making code changes that need validation

Also use when:

• User mentions MetaEditor, compilation errors, or path issues
• Exit code 1 appears (reminder: exit 1 is normal, check .ex5 file)
• Need to verify .ex5 file was created
