fix: windows install using pip mislocates share directory The setup code that tries to make the share install path absolute prependeds something like: c:\program files\python_venv to the paths. The equivalent on linux is recognized as an absolute path. On windows this is treated oddly. This resulted in the share files being placed in: c:\program files\python_venv\Lib\site-packages\program files\python_venv\share Roundup was unable to find the files there. On windows (where the platform starts with 'win') don't make the path absolute. This puts share in: c:\program files\python_venv\Lib\share and Roundup finds them. The translations and templates are found by the roundup-server. The docs are also installed under the share directory. The man pages are not installed as windows doesn't have groff to format the source documents. This is the second fix from issues getting Roundup running on windows discussed on mailing list by Simon Eigeldinger. Thread starts with: https://sourceforge.net/p/roundup/mailman/message/41557096/ subject: Installing Roundup on Windows 2023-10-05.
