rename property to the INTERFACE_ namespace for cmake <3.19 compatibility
Seems to silence:
```
CMake Error at CMake/FindGSS.cmake:360 (set_target_properties):
  INTERFACE_LIBRARY targets may only have whitelisted properties.  The
  property "CURL_PC_MODULES" is not allowed.
Call Stack (most recent call first):
  CMakeLists.txt:1306 (find_package)
