For example to build with all defaults but LUA on

cmake -G "Unix Makefiles" $INSTALL_PATH/src/server/ -DEQEMU_BUILD_LUA=ON

(Note: 0, 1, TRUE, FALSE, ON, and OFF will work here)

From the cmake manpage

-D <var>:<type>=<value>
              Create a cmake cache entry.

              When cmake is first run in an empty build tree, it creates a CMakeCache.txt file and populates it with
              customizable settings for the project.  This option may be used to specify a setting that takes prior‐
              ity  over  the  project's  default  value.   The  option  may be repeated for as many cache entries as
              desired.

edit:

OPTION(EQEMU_BUILD_SERVER "Build the game server." ON)
OPTION(EQEMU_BUILD_LOGIN "Build the login server." OFF)
OPTION(EQEMU_BUILD_AZONE "Build azone utility." OFF)
OPTION(EQEMU_BUILD_TESTS "Build utility tests." OFF)
OPTION(EQEMU_BUILD_PERL "Build Perl parser." ON)
OPTION(EQEMU_BUILD_LUA "Build Lua parser." OFF)
OPTION(EQEMU_ENABLE_BOTS "Enable Bots" OFF)
OPTION(EQEMU_SANITIZE_LUA_LIBS "Sanitize Lua Libraries (Remove OS and IO standard libraries from being able to run)." ON)

And a list that isn't copied out of the cmake file without explantions :P
