Fix typos regarding FindPython3 CMake module hint.

 If you use pyenv or pyenv-virtualenv to dynamically manage your Python version,
 you can help identify a particular version with ``pyenv version-name`` and the
 directory with ``pyenv prefix {version}``. For example::
 
-    -DPython3_ROOT=$(pyenv prefix $(pyenv version-name))
+    -DPython3_ROOT_DIR=$(pyenv prefix $(pyenv version-name))
