Please find the cluster configuration process.

Installed cmake by executing the following command.
yum -y install cmake

Still getting the following error while configuring the seastar.

[ceph: root@depressa008 build]# cmake -DWITH_SEASTAR=ON -DSeastar_CXX_FLAGS=-DSEASTAR_DEFAULT_ALLOCATOR ..
CMake Error: The source directory "/root" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.
[ceph: root@depressa008 build]#

[ceph: root@depressa008 build]#

The above I am executing on the cephadm shell.

I followed the steps mentioned in the below document.

That looks like instructions for building ceph from source. Did you actually git checkout the ceph source on that machine? I think since this bug was filed rook support was completed, so that might be the right thing to try?

I tried from the git source and got the following issue-

[root@depressa008 ceph]# WITH_SEASTAR=true ./install-deps.sh

I tried the workaround provided in the following document but failed.
