[CMake] how to add LDFLAGS BY FORCE??

[jojelino]

I DONT WANT 'CMAKE' DO DEPENDENCY STUFF. because it sucks very much.
instead of letting cmake do MORON stuff to piss me off, i want to give 
it wise and toleable solution by giving LDFLAGS stuff by hand after 
source files (surely it is external library)
such as gcc -shared -o out.exe a.o b.o c.o... -lgtk -lgdk -latk... which 
is more practical and easy to fix.

MY BUILD ENVIRONMENT IS TOTALLY MESSED UP.and i'm so so dying to find it.
