LINK_FLAGS property do not support generator expressions. In CMake 3.13, directory and target properties LINK_OPTIONS, supporting generator expressions, managed by commands add_link_options and target_link_options are introduced, .
For earlier versions you can use global variables to set flags for all targets (CMAKE_*_LINKER_FLAGS) and use target property LINK_FLAGS to override default settings (options specified by LINK_FLAGS are defined *after* those coming from global variable).
