Serghei,

I have submitted a patch for the libkscan ConfigureChecks.cmake SANE_LIBRARIES concatenation bug. Please take a look at the patch provided for http://bugs.pearsoncomputing.net/show_bug.cgi?id=901

I think this will provide a more robust set of REGEX expressions for dealing with lib and ldflag strings and will work across all distros. The original REGEX expressions simply removed spaces which would result in flags being merged together causing the build to fail. This set of REGEX expressions eliminates all non-library information first leaving only a concise semi-colon separate list of library names.

In short this is the patch:

If it works for you, go ahead and commit it.
