Description
Found when building Qt from CI-approved commit 43291fd110 in the dev branch of qt5.git.
The old qmake-based configure supports the -strip, -silent and -gcov command line option:
$ ./configure -help
...
-strip ............... Strip release binaries of unneeded symbols [yes]
...
-gcov ................ Instrument with the GCov code coverage tool [no]
...
-silent .............. Reduce the build output so that warnings and errors
can be seen more easily
...
The same options appear in the help for the new cmake-based configure. Configure appears to accept the options as valid, but then reports that it ignored them.
$ ./configure -strip
...
-- Configuring done
-- Generating done
CMake Warning:
Manually-specified variables were not used by the project:
INPUT_strip
INPUT_gcov
INPUT_silent
-- Build files have been written to: /home/qt/depot/qt5
$
A similar problem happens for -mp and -incredibuild-xge. The only difference is that these two options aren't applicable on Linux, so the old qmake-based configure helpfully warns the user about that:
WARNING: Feature incredibuild_xge is insignificant in this configuration, ignoring related command line option(s). WARNING: Feature msvc_mp is insignificant in this configuration, ignoring related command line option(s).
