[2019Q3] Cannot build libkexiv2

[BERTRAND Joël <joel.bertrand%systella.fr@localhost>]

	Hello,

	I have upgraded my pkgsrc tree (NetBSD 8.1_STABLE) and done
pkg_rolling-replace -suv to upgrade all installed packages.

	As usual, I have to fix some minor issues but I'm unable to build
libkexiv2:

-- Could NOT find Exiv2: Found unsuitable version "..", but required is
at least "0.24" (found /usr/pkg/lib/libexiv2.so)
CMake Deprecation Warning at
/usr/pkg/share/cmake-3.15/Modules/FeatureSummary.cmake:669 (message):
  SET_PACKAGE_INFO is deprecated.  Use SET_PACKAGE_PROPERTIES instead.
Call Stack (most recent call first):
  /usr/pkg/share/kde/apps/cmake/modules/MacroLogFeature.cmake:96
(SET_PACKAGE_INFO)
  CMakeLists.txt:28 (MACRO_LOG_FEATURE)

   * Exiv2 (0.24 or higher)  <http://www.exiv2.org>
     Required to build libkexiv2.

	I don't understand why cmake aborts with :
'Exiv2: Found unsuitable version ".."' Of course, exiv2 is installed:

legendre# pkg_info exiv2
Information for exiv2-0.27.2:
...

	I have seen some build issues like
https://trac.macports.org/attachment/ticket/57803/patch-FindExiv2.diff
but no one is able to fix this failure.

	Help will be welcome.

	Best regards,

	JB
