Reproducible: Always As it turns out, the following change in CMake has removed the FindX11 module from the FindOpenGL module: https://public.kitware.com/Bug/print_bug_page.php?bug_id=15268 and http://www.cmake.org/gitweb?p=cmake.git;a=commitdiff;h=d051cbda Hence, calling FindX11 in the CMakeLists.txt was all that was required to get the thing to configure properly. Attached is a patch that amends the ebuild and also fixes a slight warning annoyance in FindMiniupnpc.cmake
Created attachment 402430 [details, diff] dolphin-4.0.2-r6.patch
Can I ask what version of CMake you're using?
Seems to affect >=cmake-3.2, can you confirm that's the case for you?
Patch added and will be on the tree shortly. Thank you for the report and supplied patch :)
Yes I have CMake 3.2, and yes, the tree ebuild -r7 works correctly. Thanks!
