Sorry for the late reply
Seems you made quite a lot of progress last night (at least it was night for me).
brew install cfitsio solved the cfitsio error, but now it doesn't find libnova and I am sure it won't find the other two packages too
. Maybe the folder where I place the additional folders is wrong? I place them in the Projects folder, where also indi and build are located. However, moving them inside the indi folder doesn't help either.
I noticed that there is a homebrew version of libindi from Peter:
brew tap polakovic/astronomy
brew install polakovic/astronomy/libindi \
polakovic/astronomy/indi-qhy
I will maybe try that later.
But on macOS 10.12 there seems to be a problem with qt5 as well. It won't compile when doing brew install qt5, which is quite severe as it is needed for all the KDE stuff.
Unfortunately, I don't have a machine with 10.11 now, so I guess I will have to wait for a fix for the Qt issue.
