The lynx code doesn't know a thing about gpm.  If lynx is compile with
a suitable ncurses version, it tries to get mouse support from ncurses,
but it doesn't know anything about how the ncurses functions get mouse
input - from xterm, or from gpm functions, or maybe something completely
different.

Just linking with -lgpm isn't enough, the lynx code would have to be made
gpm-aware and call gpm functions instead of ncurses functions to get mouse
events, if you want to be able to use mouse support in the console with
ncurses but without recompiling ncurses.  I assume that's what MC does.

As long as your recompiled version is installed in a different location
(like under /usr/local) and uses a different soname you can use both.
