Why LD_LIBRARY_PATH did not work but LDFLAGS did?

Hello, a few moments ago, I tried to compile lynx. It complained about the lack of ncurses. I downloaded it, compiled it and then installed it to non standard directory.

Going back to the lynx, I expected to pass ncurses location to it through a .pc file and PKG_CONFIG_PATH. However the version of ncurses that I installed does not have . pc file.

Then I passed the location of ncurses "lib" dir to LD_LIBRARY_PATH and exported it. It did not work, lynx configure was not able to find it. Then I decided to use LDFLAGS=-L'..../ncurses/lib/'. And it did work! The question is.......why?
