This issue shows up when searching in Google for this cmake error:

For future reference: I had the same error on Ubuntu bionic. Changing -DWITH_PYTHON3=on to -DWITH_PYTHON3=3 Fixed this error for me.

Edit cmake/modules/FindCython.cmake

Replace
COMMAND ${Python${PYTHON_VERSION}_EXECUTABLE} -m cython --version

with:
COMMAND /usr/bin/python3 -m cython --version

for me what worked is to change ceph.spec file
changing:
-DWITH_PYTHON3=ON \
to
-DWITH_PYTHON3=OFF \

if want to use DWITH_PYTHON3 as ON
then it is required to :
yum install python36-Cython
and turn it back ON
assuming you are having : python3.6 installed
and then when running rpm build run it like this

rpmbuild -bb rpmbuild/SPECS/ceph.spec --define 'python3_pkgversion 36'
