Was missing the `PROPERTIES` keyword on the `Finddispatch` cmake module resulting in failures to load it correctly.

Finddispatch
|
|
------------
|
|
|
|
Find libdispatch, deferring to dispatchConfig.cmake when requested.
|
|
This is meant to find the C implementation of libdispatch for use as the
|
|
executor for Swift concurrency. This library is not intended for use by
|
|
third-party program on Linux or Windows.
|
|
|
|
Imported Targets
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
The following :prop_tgt:`IMPORTED` TARGETS may be defined:
|
|
|
|
``dispatch``
|
|
|
|
Hint Variables
|
|
^^^^^^^^^^^^^^
|
|
|
|
``swift_SDKROOT``
|
|
Set the path to the Swift SDK installation.
|
|
This only affects Linux and Windows builds.
|
|
Apple builds always use the library provided by the SDK.
|
|
|
|
``dispatch_STATIC``
|
|
Look for the libdispatch static archive instead of the dynamic library.
|
|
This only affects Linux. Apple builds always use the
|
|
dynamic library provided by the SDK. Windows does not currently have a static
|
|
libdispatch implementation.
|
|
|
|
Result Variables
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
The module may set the following variables if `dispatch_DIR` is not set.
|
|
|
|
``dispatch_FOUND``
|
|
true if dispatch headers and libraries were found
|
|
|
|
``dispatch_INCLUDE_DIR``
|
|
the directory containing the libdispatch headers
|
|
|
|
``dispatch_LIBRARIES`` OR ``dispatch_IMPLIB``
|
|
the libraries to be linked
|
|
|
|
#]=======================================================================]
|
|
|
|
# If the dispatch_DIR is specified, look there instead. The cmake-generated
|
|
# config file is more accurate, but requires that the SDK has one available.
|
