cause the LINK_INTERFACE to be empty for all shared library targets be
accepted into CMake?
Sure. I think the simplest interface is to define a variable whose value
is used as the property default for LINK_INTERFACE_LIBRARIES:
set(CMAKE_LINK_INTERFACE_LIBRARIES "")
Look in cmTarget.cxx for the method cmTarget::SetMakefile. There are a
bunch of calls to "SetPropertyDefault". Just add one like
this->SetPropertyDefault("LINK_INTERFACE_LIBRARIES", 0);
This tells CMake to use the value of the variable
CMAKE_LINK_INTERFACE_LIBRARIES
as the default LINK_INTERFACE_LIBRARIES when the target is created.
The ",0" argument means that there is no default if the variable is
not set.
Then add appropriate documentation for the variable in cmDocumentVariables
and add a sentence to the original property documentation about how the
default is defined.
