VS: unsetting CMAKE_IMPORT_LIBRARY_SUFFIX generates broken visual studio targets
The filename for the import library is not generated, resulting in an 'Import Library' that is set to a folder corresponding to the 'Output Directory' ('Import Library' found in in Project Properties->Linker->Advanced)
example: Given a source/binary dir of: 'R:/wip/cmake' the 'Import Library' will be set to 'R:/wip/cmake/Debug/' for the Debug config.
Attached minimal files to reproduce:
cmake -G "Visual Studio 16 2019"
