The reason for the error is incorrectly specified link dependencies
for mysql_embedded, mysqltest_embedded and mysql_client_test_embedded
in CMakeLists.txt (ADD_DEPENDENCIES should be TARGET_LINK_LIBRARIES)


libmysqld/CMakeLists.txt:
  changed library type for libmysqld to SHARED instead of
  MODULE. MODULE in CMake notation is a shared library that 
  is used only in dlopen/dlsym/LoadLibrary scenarios.
  Hence it was impossible to use TARGET_LINK_LIBRARIES with
  a MODULE.
libmysqld/examples/CMakeLists.txt:
  Use TARGET_LINK_LIBRARIES (instead of previously incorrectly 
  used ADD_DEPENDENCIES) to specify link dependency from libmysqld
