Help: Fix --build-and-test synopsis in ctest(1)
The synopsis added by !1427 (merged) is missing the actual
--build-and-test argument! Add it now.
@reviewer please check if I actually understood this right.
Low in the manual, where the build options are discussed, the syntax is shown as
ctest --build-and-test <source> … while at the top of the manual
ctest <source> <build> is suggested. Trying the latter on my system does not seem to be a sensible instruction: when in a cmake build dir, tests are run and arguments are ignored, when in an empty dir, no build is launched. Thus I concluded:
ctest <source dir> <build dir> should be
ctest --build-and-test <source dir> <build dir>
