Title: Fix copy files in cpp-empty-test in MSVC build

I had problems when compiling cpp-tests with MSVC. And I spotted one mistake here.
Must change from

${CMAKE_CURRENT_SOURCE_DIR}/../../../external/<.........>

to

${CMAKE_CURRENT_SOURCE_DIR}/../../external/<.........>

because `${CMAKE_CURRENT_SOURCE_DIR}` is `/tests/cpp-empty-test/`.
