As a result all cmake package detection calls will fail with errors such as | By not providing "FindOpenCV.cmake" in CMAKE_MODULE_PATH this project has | asked CMake to find a package configuration file provided by "OpenCV", but | CMake did not find one. Expected behavior ----------------- cmake project will be built as on native host. 64869 1 richard.purdie 2016-08-04 14:44:59 +0000 Looking at cmake.bbclass, it looks like this *is* target specific, list(APPEND CMAKE_MODULE_PATH "${STAGING_DATADIR}/cmake/Modules/") which means we make need to install target cmake modules files into the sdk in order to support cmake? 67089 2 ross.burton 2016-10-10 16:19:56 +0000 So I've spent *way* too long learning all about the horrible ways that cmake does stupid things to piss you off. That message is *so* misleading it's not even funny. I'll note that for some reason the cmake files for opencv are part of opencv-apps, so it's entirely possible that they're not in the SDK. Can you verify that you have a /usr/share/OpenCV/OpenCVConfig.cmake inside your SDK's target sysroot? 67092 3 ross.burton 2016-10-10 16:32:11 +0000 https://patchwork.openembedded.org/patch/132795/ is my fix to opencv to put the cmake files into opencv-dev. 67195 4 henry.bruce 2016-10-12 23:45:21 +0000 Nice work. Ross. I have validated that the patch solves the problem. I'll leave open until patch is merged into meta-oe. How do I request a backport for krogoth? 67198 5 ross.burton 2016-10-13 08:39:47 +0000 Once it's merged remind me and I'll backport it. 67364 6 ross.burton 2016-10-19 15:06:24 +0000 Marking as 2.2 as this isn't actually a oe-core but, but meta-oe. 67723 7 ross.burton 2016-10-28 13:15:48 +0000 Fix to opencv merged in meta-oe fded4cf6a8cf1ff065af97f3283b55aeba458d28.
