It seems that you do the right thing.

I think you could have an issue because the source is in C++. You have 
to tell to the C++ compiler that it's a C function.

I think it can be done by using the header file of the library (I 
suppose #include <strl.h>) which should declare all functions within 
"extern "C" {" and "}" to indicate that all these are C functions. If 
it's not done you can do it yourself.

To check you can just add the following line in loadfiles.cxx and try to 
build your program.
"extern "C" size_t strlcpy(char *dst, const char *src, size_t len);"


Else, you have $(LIBSTRL_LIBS) in the library field of your target so it 
looks fine. You can check LIBSTRL_LIBS in the makefile generated by 
autotools, it should be equal to -lstrl or something similar.

When a library isn't provided as a package, you need to add 
-l_library_name to the linker flags. I think it's the case foe libbz2.
