The --trace option is helpful, but sometimes, what you're looking for is deep under many layers of function calls and figuring out what instance of the function call you're looking at is tedious to determine (usually involving patching and message()). Instead, add a --trace-expand option to trace while expanding commands into what CMake actually sees.
