Subject: [PATCH 1/2] Fix building without Ceres

When `find_package` is run in the subdirectory, the variables
will be altered in the scope of subdirectory, and the
toplevel values are not affected, and ConfigLocal.h will
have incorrect defines.

Remove the additional CERES_INCLUDE_DIRS and CERES_DEFINITIONS,
these are automatically set when adding Ceres to the
`target_link_libraries(MVS ...)`.
