Subject: CMakeLists.txt: increase verbosity for selected allocator
X-Git-Tag: v19.0.0~1089^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=e6d56c1effc54006cc9367c7afa6e7d2c64194b6;p=ceph.git

CMakeLists.txt: increase verbosity for selected allocator

Unless the allocator was set on command line, we will select one based on the following order:
```
"specify memory allocator to use. currently tcmalloc, tcmalloc_minimal, \
jemalloc, and libc is supported. if not specified, will try to find tcmalloc, \
and then jemalloc. If neither of then is found. use the one in libc.")
```
with this change, cmake will explicitly message the compiler selected,
otherwise we have no option to identify the one which is being used.
