yes true.
You may relax the CMake dependency by editing the UseRPMTools.cmake
file and suppress the line:

BuildRequires:	cmake

That pretty right.
But in fact source RPM includes sources :=)
That source RPM will be used to generate a binary RPM
for going from source RPM to --> binary RPM
you WILL USE CMake as you already do it for compiling
your source.
That why the dependency is included.

This is rpmbuild which requires CMake to be installed as an rpm.
This is so because the spec file:
      - generated by UseRPMTool.cmake
      and
      - used by rpmbuild

indicates:

BuildRequires:	cmake
