Your command is almost correct.  You only need to set
CMAKE_EXE_LINKER_FLAGS, because CMAKE_SHARED_LINKER_FLAGS is used for
linking shared libraries.

Or you need to set both if you plan to use a shared library that needs
pcre (like ha_mroonga.so or libmysqld.so).

And you don't need to specify -lpcre, cmake adds it automatically and as
necessary.
