Hello could you please help with my errors? I have been at this for days trying to install caffe, first via make, now via cmake gui. I do not understand what is the matter with permissions: I have gone to the files about which the complaint is and they are all ‘read and write’. I have now added ‘read and write’ across the board for all users/admin etc, but still same issue. I am on MacBook Pro, Catalina. Trying to install with Anaconda and CPU only. Here is my output from cmake gui:

Error in configuration process, project files may be invalid.

launch CMake Gui as admin. Or change installation location.

It looks like the build tree is on a `.dmg` view or something. A different build directory in a writable location would be better.
