Version ' glibcxx_3.4.21 ' not found solution

When the installation cmake3.5.1 runs./bootstrap, the following prompts appear:

Gmake: "CMake" is up to date.
/usr/soft/cmake-3.5.1/bootstrap.cmk/cmake:/lib64/libstdc++.so.6:version ' glibcxx_3.4.21 ' not found (required By/usr/soft/cmake-3.5.1/bootstrap.cmk/cmake)

Error when bootstrapping CMake:
Problem while running initial CMake

Missing glibcxx_3.4.21, or later version
To verify the version issue:

The current version of the glibcxx_3.4.21 did not find, but I just installed a gcc5.3.0
Along with the installation path for GCC, a new libstdc++ was found:

Here is the need to have a soft link to the right place, just fine.
