Dear Maintainer,
Any CMake project that calls find_package(Gmic) fails at the generate step
with:
CMake Error at /usr/lib/x86_64-linux-gnu/cmake/gmic/GmicTargets.cmake:71
(set_target_properties):
The link interface of target "libgmic" contains:
CImg::CImg
but the target was not found.
GmicTargets.cmake exports libgmic with CImg::CImg in its link interface, but
no package on the system provides that imported target, and GmicConfig.cmake
does not call find_package for it. Installing cimg-dev does not help --
cimg-dev ships the header only, not a CMake config defining CImg::CImg.
This makes libgmic-dev unusable for linking against system G'MIC from CMake.
Steps to reproduce:
1. sudo apt install libgmic-dev
2. Create a CMakeLists.txt containing:
cmake_minimum_required(VERSION 3.20)
project(t)
find_package(Gmic REQUIRED)
3. cmake -S . -B build
Expected: configuration succeeds.
Actual: fails as above.
I hit this while building the G'MIC-Qt plugin for Krita with
-DENABLE_SYSTEM_GMIC=ON. Building the engine from upstream source works, so
the problem is confined to the CMake export in the Debian package.
Possible fixes: ship a CMake config for CImg providing the CImg::CImg target,
add a find_dependency() call in GmicConfig.cmake, or drop CImg::CImg from the
exported link interface if the dependency is header-only and already handled
via include directories.
