Fixes#192617. The breakage is introduced by a glslang update. Now
`${glslang}/lib/cmake/OSDependentTargets.cmake` points to
`${glslang}/share/glslang/glslang-targets.cmake`. The latter requires
the `SPIRV-Tools-opt` target. So the two lines in patch should be moved
before `OSDependentTargets.cmake`.
This also fixes a breakage introduced by cmake described in #144170.
