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. Signed-off-by: Simon McVittie <smcv@collabora.com>
