Build with CMAKE_SHARED_LINKER_FLAGS=" -Wl,--no-undefined"

[awissu]

Hello!
GCC complains that it can't build the library with undefined symbols:

[ 193s] CMakeFiles/enginephonon.dir/enginephonon_automoc.cpp.o:(.data.rel.ro+0x0): undefined reference to `EngineBase::staticMetaObject'
[ 193s] collect2: error: ld returned 1 exit status
[ 193s] src/core/player/phonon/CMakeFiles/enginephonon.dir/build.make:125: recipe for target 'lib/libenginephonon.so' failed
[ 193s] make[2]: *** [lib/libenginephonon.so] Error 1

you can try this:

cmake .. \
  -DUSE_SYSTEM_QTSINGLEAPPLICATION:BOOL=ON \
  -DUSE_SYSTEM_QXT:BOOL=ON \
  -DCMAKE_SHARED_LINKER_FLAGS="-Wl,--as-needed"

Yes, the build succeeded.
But if I use %cmake macro this induces errors when building:

rpm --eval %cmake|grep -i shared
-DCMAKE_SHARED_LINKER_FLAGS="-Wl,--as-needed -Wl,--no-undefined -Wl,-z,now" \
