This is just a draft

Proposal: update %cmake rpm macro to set: CMAKE_INSTALL_LIBDIR, INCLUDE_INSTALL_DIR, LIB_INSTALL_DIR, SYSCONF_INSTALL_DIR, SHARE_INSTALL_PREFIX

<!-- /etc/rpm/macros.cmake:
-->
#
#
%_cmake_lib_suffix64 -DLIB_SUFFIX=64
%__cmake %{_bindir}/cmake

%cmake \
CFLAGS="${CFLAGS:-%optflags}" ; export CFLAGS ; \
CXXFLAGS="${CXXFLAGS:-%optflags}" ; export CXXFLAGS ; \
FFLAGS="${FFLAGS:-%optflags}" ; export FFLAGS ; \
%__cmake \\\
-DCMAKE_INSTALL_PREFIX:PATH=%{_prefix} \\\
-DCMAKE_INSTALL_LIBDIR:PATH=%{_libdir} \\\
-DINCLUDE_INSTALL_DIR:PATH=%{_includedir} \\\
-DLIB_INSTALL_DIR:PATH=%{_libdir} \\\
-DSYSCONF_INSTALL_DIR:PATH=%{_sysconfdir} \\\
-DSHARE_INSTALL_PREFIX:PATH=%{_datadir} \\\
%if "%{?_lib}" == "lib64" \
%{?_cmake_lib_suffix64} \\\
%endif \
-DBUILD_SHARED_LIBS:BOOL=ON

Consideration: Now that LIB_INSTALL_DIR is used, the %_cmake_lib_suffix64 hackery (-DLIB_SUFFIX=64) could possibly be omitted. I'm not advocating that, since I see no harm in setting both LIB_INSTALL_DIR and LIB_SUFFIX.
