before this change, we assume that the variable set if rados::radospp is
found will be radospp_FOUND, but this is a feature cmake 3, see
https://cmake.org/cmake/help/v3.3/module/FindPackageHandleStandardArgs.html
while the cmake shipped by centos is cmake 2.8.12, where the variable
name will be <UPPERCASED_NAME>_FOUND, see
https://cmake.org/cmake/help/v2.8.12/cmake.html#module:FindPackageHandleStandardArgs
in the test of test_envlibrados_for_rocksdb.sh, we are using cmake not
the cmake3 offered by EPEL7, so RADOSPP_FOUND will be set instead. that's why
executable env_librados_test will fail to link against rados::radospp.
as rados::radospp won't be defined if radospp_FOUND is not defined/set.
after this change, the 2nd mode of FIND_PACKAGE_HANDLE_STANDARD_ARGS()
is used instead to ensure that radospp_FOUND is defined even if cmake
2.8.12 is used.
also, the message() commands for debugging purpose are removed.
