cmake: remove empty strings from FetchContent

remove empty strings from FetchContent to eliminate cmake build warnings like this:

CMake Warning (dev) at /usr/share/cmake/Modules/FetchContent.cmake:1564 (cmake_parse_arguments):
  The BUILD_COMMAND keyword was followed by an empty string or no value at
  all.  Policy CMP0174 is not set, so cmake_parse_arguments() will unset the
  ARG_BUILD_COMMAND variable rather than setting it to an empty string.
