Yes, but if it also has a "project(EO)" then CMake will define
EO_SOURCE_DIR automatically at that point to be the same as the
directory that contains the CMakeLists that has that "project(EO)" in
it...
You wouldn't want to try to override that with something different,
because the writer of the CMakeLists file is counting on the value of
it.
Also, if there is a "set(EO_SOURCE_DIR "some_value")" in there, then
the value in the CMakeLists file will locally override whatever you
pass in on the command line.
HTH,
