Changeset 21105 breaks win32 compilation of mythmusic

[Jonathan Martens <jonathan@…>]

I know mythmusic does not compile at the moment, but I was trying to do so until I got hit by the output of the ./configure statement that taglib 1.5 is now needed.

Some investigation leads to [21105] where the determination of the taglib version is done.

Since taglib requires cmake as of version 1.5 the win32-packager.pl script was adapted to use pre-compiled binaries (of which the source is clear, but the resposible person is not). These pre-compiled binaries do not include taglib-config and therefore the configure fails either:

1. because only taglib 1.5 is installed and therefore taglib-config can not be found
2. because of taglib 1.5 might be installed over an older taglib directory, which therefore still has an old version of taglib-config as this is not overwritten.

Attached patch is to overcome this problem, at least on windows.

(In [21909]) Assume taglib 1.5 if no taglib-config. Currently only a problem on Windows. Closes #6793
