I got quite bored by fixing issues one by one adjusting spec files wrt
cmake usage. Thus I went out and wrote cmake.macros for our beloved cmake
and put it into my home project [1].
Basically now you just call %cmake -Dmydef=on -Dsomethingelselocal=/var/
instead of having to fiddle with all the variables yourself.
Have you attempted using -DCMAKE_C_FLAGS_RELEASE:STRING="%optflags"?
That might in theory work, but the best we thought up for gentoo was to create 
own target because this always caused some issues.

Basically you put there something like

-DCMAKE_USER_MAKE_RULES_OVERRIDE="/path/opensuse.cmake"

And then override whole set.
What I wrote in Gentoo:

        local build_rules=${BUILD_DIR}/gentoo_rules.cmake
        cat > "${build_rules}" <<- _EOF_
                SET (CMAKE_AR $(type -P $(tc-getAR)) CACHE FILEPATH "Archive 
manager" FORCE)
                SET (CMAKE_ASM_COMPILE_OBJECT " <DEFINES> 
${CFLAGS} <FLAGS> -o <OBJECT> -c <SOURCE>" CACHE STRING "ASM compile command" 
FORCE)
                SET (CMAKE_C_COMPILER $(type -P $(tc-getCC)) CACHE FILEPATH "C 
compiler" FORCE)
                SET (CMAKE_C_COMPILE_OBJECT " <DEFINES> 
${CPPFLAGS} <FLAGS> -o <OBJECT> -c <SOURCE>" CACHE STRING "C compile command" 
FORCE)
                SET (CMAKE_CXX_COMPILER $(type -P $(tc-getCXX)) CACHE FILEPATH 
"C++ compiler" FORCE)
                SET (CMAKE_CXX_COMPILE_OBJECT " <DEFINES> 
${CPPFLAGS} <FLAGS> -o <OBJECT> -c <SOURCE>" CACHE STRING "C++ compile 
command" FORCE)
                SET (CMAKE_RANLIB $(type -P $(tc-getRANLIB)) CACHE FILEPATH 
"Archive index generator" FORCE)
                SET (PKG_CONFIG_EXECUTABLE $(type -P $(tc-getPKG_CONFIG)) 
CACHE FILEPATH "pkg-config executable" FORCE)
        _EOF_

Basically we could install this rule file with cmake too and then just make 
sure its used.
