Bug#840329: taglib-extras: FTBFS: CMake Error at cmake/modules/FindTaglib.cmake:132 (message): Could not find Taglib

[Stuart Prescott]

Control: tags -1 + patch

The existing FindTaglib.cmake in this package uses the STRLESS function for 
lexical comparison of the version strings rather than using VERSION_LESS. It 
thus (wrongly) concludes that the minimum version requirement of 1.6 was not 
met when it finds version 1.11 installed.

-- TagLib version not found: version searched :1.6, found 1.11
CMake Error at cmake/modules/FindTaglib.cmake:132 (message):
  Could not find Taglib

The attached patch corrects this test allowing the package to build 
successfully.

cheers
Stuart

GPG fingerprint90E2 D2C1 AD14 6A1B 7EBB 891D BBC1 7EBB 1396 F2F7Description: Fix version comparison for finding taglib

Existing cmake code doesn't do the min version comparison correctly.
