From bb399cd140e1b22f46b019f9b0bc14e62b270ab7 Mon Sep 17 00:00:00 2001 From: Wolfgang Bauer Date: Tue, 14 Dec 2021 17:02:22 +0100 Subject: [PATCH] Revert "Exiv2 is now released with exported targets using cmake rules. No need to have a dedicated find exiv2 cmake script. Bump minimal version to 0.27.1" This reverts commit 06e77271d72fe5e4abeb38641f3addc2cfbff126. Also, it replaces the use of `Exiv2::XmpData::eraseFamily()` (new in exiv2-0.27) with inline code copied from exiv2-0.27.5. Fixes build on Leap 15.x which only have exiv2 0.26. --- core/CMakeLists.txt | 14 +-- core/app/DigikamCoreTarget.cmake | 2 +- core/cmake/modules/FindExiv2.cmake | 116 ++++++++++++++++++ core/libs/metadataengine/CMakeLists.txt | 10 +- .../metadataengine/engine/metaengine_xmp.cpp | 23 +++- 5 files changed, 148 insertions(+), 17 deletions(-) create mode 100644 core/cmake/modules/FindExiv2.cmake diff --git a/core/CMakeLists.txt b/core/CMakeLists.txt index 16bba83335..174dc3c683 100644 --- a/core/CMakeLists.txt +++ b/core/CMakeLists.txt @@ -16,7 +16,7 @@ message(STATUS "") set(KF5_MIN_VERSION "5.5.0") set(QT_MIN_VERSION "5.9.0") -set(EXIV2_MIN_VERSION "0.27.0") +set(EXIV2_MIN_VERSION "0.26") set(OPENCV_MIN_VERSION "3.3.0") set(LENSFUN_MIN_VERSION "0.2.6.0") # For Lens auto-correction plugin set(QTAV_MIN_VERSION "1.12.0") # For video support. @@ -188,7 +188,7 @@ endif() -find_package(exiv2 REQUIRED) +find_package(Exiv2 ${EXIV2_MIN_VERSION} REQUIRED) set_package_properties("exiv2" PROPERTIES DESCRIPTION "Required to build digiKam" @@ -197,10 +197,6 @@ PURPOSE "Library to manage image metadata" ) -if("${exiv2_VERSION}" VERSION_LESS ${EXIV2_MIN_VERSION}) - message(FATAL_ERROR "Exiv2 version is too old (${exiv2_VERSION})!
