CTEST_PROGRESS_OUTPUT

在 3.13 版被加入.

這是一個 CMake 環境變數。其初始值取自呼叫的進程環境。

Boolean environment variable that affects how ctest command output reports overall progress. When set to 1, TRUE, ON or anything else that evaluates to boolean true, progress is reported by repeatedly updating the same line. This greatly reduces the overall verbosity, but is only supported when output is sent directly to a terminal. If the environment variable is not set or has a value that evaluates to false, output is reported normally with each test having its own start and end lines logged to the output.

The --progress option to ctest overrides this environment variable if both are given.
