The thing with options in cmake is the values it takes are boolean only.
To do what you want I think you have to do something along the lines of this.
if(NOT DEFINED SHELL_PATH)
set(SHELL_PATH  <default value> CACHE STRING "path to POSIX compliance shell")
endif()

Then if you want to change this value, edit this value in CMakeCache.txt.

Ah, this is what I mean, I think it's better to use this (without
if_not_define)

	set(SHELL_PATH  "/bin/sh" CACHE PATH "path to POSIX compliance shell")

Then, we can use this:

	cmake -DSHELL_PATH=/path/to/good/sh ...
