Subject: [PATCH] [ports.cmake] Fixup capitalization inconsistencies of Windows
 drive letter. (#8304)

CMAKE_CURRENT_LIST_DIR reflect current directory. Thus It can be lowercase drive letter.
The lowercase drive letter cause #8237 issue.
Fixup drive letter to uppercase by using get_filename_component().
