Hello, Firstly, you should file a bug, but that might not get it working as quickly as you'd like.

If you edit them system-wide, you can likely get everything to build via Portage. You can also look for a "taget_link_library" directive in the project's CMakeLists.txt and hardcode a path. https://cmake.org/cmake/help/v3.0/command/target_link_libraries.html > I'd be grateful to any hints and links (for 'cmake' dummies) > Pretending you want to configure and build your project with CMake is probably the best option, though I have given you all that you should need to fix the problem. https://cmake.org/cmake-tutorial/ I would seriously consider Mr. Dang's solution. It is something I have had to do quite a bit, especially as CMake is extremely opaque at the system level. Brewlinux is new to me, I just do everything by hand. Cheers, R0b0t1
