Subject: [PATCH] Do not prepend /usr to libexecdir

Fix #276

Without this patch, compiling with -DCMAKE_INSTALL_LIBEXECDIR=%{_libexecdir}
expanded this to /usr//usr/lib/ckb-next-animations

and there is no rpm macro to have libexecdir without /usr
but we need to use these macros to be able to use the same .spec file
across distributions (Fedora has /usr/libexec and openSUSE has /usr/lib )

This matches usage in src/daemon/CMakeLists.txt
