With the classic GLOB search, it is trivial to remove items from the
result list:
LIST(REMOVE_ITEM files
  ${CMAKE_CURRENT_SOURCE_DIR}/main.c
  ${CMAKE_CURRENT_SOURCE_DIR}/test.c)

With the GLOB_RECURSE command, it is more tricky. But you can filter
items by using regular expressions:

FILE(GLOB_RECURSE files "*.c")
FOREACH(item ${files})
  IF(${item} MATCHES "foo/main.c")
    LIST(REMOVE_ITEM files ${item})
  ENDIF(${item} MATCHES "foo/main.c")
ENDFOREACH(item)
MESSAGE(STATUS "${files}")
