cmake

[Pete Zaitcev <zaitcev@redhat.com>]

Dear All:

I'm trying to run cmake, in order to make sure my patches do not break it
(in particular WIP 5073 added source files). Result looks like this:

[zaitcev@lembas ceph-tip]$ cmake src

[zaitcev@lembas ceph-tip]$ rpm -qa | grep -i cmake
extra-cmake-modules-5.16.0-1.fc23.noarch
cmake-3.3.2-1.fc23.x86_64
[zaitcev@lembas ceph-tip]$ 

Is this expected? Is my cmake incantation wrong?

Thanks,
