[CMake] Fix #763 reported by @jirislaby.

Browse source 
`INTERFACE` was the not appropriate usage requirement to use. However
it only caused a problem when USE_LIB_GMP was enabled. With `INTERFACE`
`-lgmp` was not specified on the link line so `libz3.so` did not have a
reference to the library and linking against `libz3.so` by clients
would fail with missing references to symbols in `libgmp`.
