Subject: [PATCH] cmake: add import library to custom command OUTPUT

Ninja requires all produced files to be listed as explicit outputs of
custom commands. The zig build produces a .lib import library alongside
the DLL, but it was not listed in the OUTPUT directive. This causes
Ninja to fail with "missing and no known rule to make it" when
IMPORTED_IMPLIB references the .lib file.
