fixed module globbing to only exclude directories based on name instead of full path

modules/CMakeLists.txt

 # recursively process all subdirectories
 file(GLOB ALL_FILES *)
-foreach(fname ${ALL_FILES})
+foreach(full_name ${ALL_FILES})
+  get_filename_component(fname ${full_name} NAME)
   if(NOT ${fname} MATCHES ".*\\.svn" 
      AND NOT ${fname} MATCHES ".*CMakeFiles" 
      AND NOT ${fname} MATCHES ".*main"
      AND NOT ${fname} MATCHES "doc")
-      if(IS_DIRECTORY ${fname})
+      if(IS_DIRECTORY ${full_name})
         add_subdirectory(${fname})
