[CMake] Links to online documentation of CMake broken

[Andreas Schuh]

Hi,

I noticed that the CMake documentation online has been updated and the
URLs have changed. The main links are correctly rewritten to the new
URLs, but the references to particular sections of the documents are
discarded during this rewrite. This breaks many links in my
documentation where I link directly to the corresponding documentation
of the CMake commands.

For example, the link
http://www.cmake.org/cmake/help/cmake-2-8-docs.html#command:find_package
is rewritten to http://www.cmake.org/cmake/help/v2.8.8/cmake.html
instead of http://www.cmake.org/cmake/help/v2.8.8/cmake.html#command:find_package.
