If enabled the following targets will be created:
* `${SPIRV_TOOLS}-static` - `STATIC` library. Has full public symbol visibility.
* `${SPIRV_TOOLS}-shared` - `SHARED` library. Has default-hidden symbol visibility.
* `${SPIRV_TOOLS}` - will alias to one of above, based on BUILD_SHARED_LIBS.
If disabled the following targets will be created:
* `${SPIRV_TOOLS}` - either `STATIC` or `SHARED` based on the new `SPIRV_TOOLS_LIBRARY_TYPE` flag. Has full public symbol visibility.
* `${SPIRV_TOOLS}-shared` - `SHARED` library. Has default-hidden symbol visibility.
Defaults to `ON`, matching existing build behavior.
This flag can be used by package maintainers to ensure that all libraries are built as shared objects.
