Freeimage plugin not building

[KonradNoTantoo]

Hey!

Thanks for the great job you did here. I managed to run a test app on 13.4.0 in not much time.

However, I noticed a small issue with the freeimage plugin build option activated. Findfreeimage.cmake seems to be doing its job, and related variables look like what's expected, but the plugin DLL file is not built.

I noticed this when trying to replace your version of freeimage with the package on conancenter (it's quite new there). I observe the same behavior using theirs or yours. I thought you may want to know stuff like that. I've also found a few other issues will trying to build, so tell me whether to open other issues here (or not, or whatever else is most convenient for you). Some of them seem to be caused by Ogre itself, but it's hard to be certain without digging further.

Here's my configuration:

[settings]
arch=x86_64
arch_build=x86_64
build_type=Release
compiler=Visual Studio
compiler.runtime=MD
compiler.version=17
os=Windows
os_build=Windows

Here's my test command (after adding your remote to conan):

conan install -b missing -o ogre3d:with_freetype=True -o ogre3d:with_sdl=True -o ogre3d:with_qt=False -o ogre3d:install_samples=True -o ogre3d:install_tools=True -o ogre3d:bindings_csharp=False -o ogre3d:bindings_java=False -o ogre3d:bindings_python=False -o ogre3d:rendersystem_direct3d11=True -o ogre3d:rendersystem_direct3d9=True -o ogre3d:rendersystem_metal=False -o ogre3d:rendersystem_opengl=True -o ogre3d:rendersystem_opengl3=True -o ogre3d:rendersystem_opengles=False -o ogre3d:rendersystem_tiny=False -o ogre3d:rendersystem_vulkan=False -o ogre3d:plugin_assimp=True -o ogre3d:plugin_bsp=True -o ogre3d:plugin_dotscene=True -o ogre3d:plugin_exrcodec=True -o ogre3d:plugin_freeimage=True -o ogre3d:plugin_glslang=True -o ogre3d:plugin_octree=True -o ogre3d:plugin_particlefx=True -o ogre3d:plugin_pcz=True -o ogre3d:plugin_stbi=True -o ogre3d:component_bites=True -o ogre3d:component_meshlodgenerator=True -o ogre3d:component_overlay=True -o ogre3d:component_overlay_imgui=True -o ogre3d:component_paging=True -o ogre3d:component_property=True -o ogre3d:component_rtshadersystem=True -o ogre3d:component_terrain=True -o ogre3d:component_volume=True -o ogre3d:enable_astc=True -o ogre3d:enable_dds=True -o ogre3d:enable_double=False -o ogre3d:enable_etc=True -o ogre3d:enable_gl_state_cache_support=True -o ogre3d:enable_gles2_glsl_optimiser=True -o ogre3d:enable_meshlod=True -o ogre3d:enable_node_inherit_transform=False -o ogre3d:enable_pvrtc=True -o ogre3d:enable_quad_buffer_stereo=False -o ogre3d:enable_viewport_orientationmode=False -o ogre3d:enable_zip=True -o ogre3d:build_tests=False --require-override zlib/1.2.12 ogre3d/13.4.0@sintef/stable

Thanks for letting us know! (And sorry for the late response.) Feel free to open more issues. We can't promise that they will get fixed anytime soon; we only have the capacity to fix problems when they directly affect our own work. But a bug report is useful both for us and for other users who should be aware of the issues, and it's also a good way for us to notify our users when the bugs eventually get fixed.

Thanks for the great job you did here.

Actually, I think we should be thanking you for your work. I just realised that you are the author of the package recipe we forked to create this one. :)
