the plain signature for target_link_libraries has already been used with X

[snweiss]

A "the plain signature for target_link_libraries has already been used with ..." error is generated when trying to add private link dependencies after a target was generated with wdk_add_driver :

wdk_add_driver(driver WINVER 0x0A00)
target_link_libraries(driver PRIVATE WDK::WDMSEC)

This can be workaround by just removing the "PRIVATE" option but our use-case is slightly more complex since the link dependencies are set by down-stream cmake infrastructure files that are shared among different projects.

This is the patch that we're currently using to mitigate the issue

Yes, target_link_libraries should be modernized to specify visibility (private, public, interface). Thanks for reporting!
