So, basically we this:
set(CMAKE_LINK_INTERFACE_LIBRARIES "")
add_library(libA SHARED classA.cpp)
add_library(libB SHARED classB.cpp)
add_library(libC SHARED classC.cpp)
generate_export_header(libA)
generate_export_header(libB)
generate_export_header(libC)
target_link_libraries(libB libA)
target_link_libraries(libC libA libB)
add_executable(exec
"main.cpp"
)
target_link_libraries(exec libC )
So, setting CMAKE_LINK_INTERFACE_LIBRARIES to "" is supposed to make the
transitive linking of A and B not happen when linking C. I tried adding
some print stuff in the code. But, I am not sure where to look.
I added the following:
void cmTarget::SetPropertyDefault(const char* property,
const char* default_value)
{
+ bool debug = false;
+ if(strcmp("LINK_INTERFACE_LIBRARIES", property) == 0)
+ debug = true;
+ if(debug) std::cerr << this->GetName() << "\n";
// Compute the name of the variable holding the default value.
std::string var = "CMAKE_";
var += property;
-
+ if(debug) std::cerr << var << "\n";
if(const char* value = this->Makefile->GetDefinition(var.c_str()))
{
+ if(debug) std::cerr << "found it " << value << "\n";
this->SetProperty(property, value);
}
else if(default_value)
{
+ if(debug) std::cerr << "not found " << default_value << "\n";
this->SetProperty(property, default_value);
}
}

I ended up with this:
libA
CMAKE_LINK_INTERFACE_LIBRARIES
found it
libB
CMAKE_LINK_INTERFACE_LIBRARIES
found it
libC
CMAKE_LINK_INTERFACE_LIBRARIES
found it
libB Not doing interface
libC Not doing interface
libC Not doing interface
Do you have other prints that I should add? How is this supposed to work?
