This seems like a common problem:

Error checking out rtmidi when building

CMake Error at rtmidi-subbuild/rtmidi-populate-prefix/tmp/rtmidi-populate-gitclone.cmake:49 (message): Failed to checkout tag: '806e18f575b68c23b26f9398e1b6866b335b5308'

Changing the tag to '6.0.0' in CMakeLists.txt seems to work.
