cmake: Fix static linking to dependencies with "-" in library name 

When SDL is built with Wayland support on Linux, and Wayland libraries
are linked as dependencies instead of being loaded with dlopen(), its
dependencies will include libraries whose names contain a dash, like
`-lwayland-client` and `-ldecor-0`. Don't replace such libraries with
`-lwayland` and `-ldecor`: those don't exist and linking them will fail.
