I have pushed new branch stage/compact-status-log for review.
Idea behind is to reduce cmake output when we are in terminal. When we are
outputting message "Trying feature" we can later remove it when new output
comes using ANSI escape codes. This is done by appending (but not flushing)
\e[9999D\e[K to stdout. Once new status comes and flushes stdout (explicitly or
implicitly by \n) these codes will be executed and will clear the line, so we
get:
Trying some feature - success
Instead of:
Trying some feature
Trying some feature - success
NOTE this behavior only applies to terminal (isatty check), so when piping
cmake output to file is works as before.
Waiting for your feedback.

Use message(CLEAR "...") when starting checks
This emits more compact logs when cmake is running in terminal.

message(...) function now accepts CLEAR keyword
Status text emitted with message(CLEAR "...") will be immediately cleared
when
next stdout output arrives. This ensures we get more compact message logs,
e.g.:
Trying some feature - success
Instead of:
Trying some feature
Trying some feature - success
