# CMAKE_MESSAGE_CONTEXT_SHOW

Setting this variable to true enables showing a context with each line logged by the `message()` command (see `CMAKE_MESSAGE_CONTEXT` for how the context itself is specified).

This variable is an alternative to providing the `--log-context` option on the `cmake` command line. Whereas the command line option will apply only to that one CMake run, setting `CMAKE_MESSAGE_CONTEXT_SHOW` to true as a cache variable will ensure that subsequent CMake runs will continue to show the message context.

Projects should not set `CMAKE_MESSAGE_CONTEXT_SHOW`. It is intended for users so that they may control whether or not to include context with messages.
