stellarium360 on Linux Mint 18.1

Linux Mint 18.1 Cinnamon works fine, dual booting with Mac OS 10.6.8 Snow Leopard, on an i7 Macbook Pro. Mageia Linux, the recommended option for Stellarium360, blanks the screen and / or crashes the system while trying to boot. So, tried compiling Stellarium360 on Linux Mint 18.1. But ran into problems.

ran the install dependencies for Ubuntu script, and ran ./configure. Configure complains that
checking for SDL2/SDL_image.h... yes
checking GL/glew.h usability... yes
checking GL/glew.h presence... yes
checking for GL/glew.h... yes
checking for ptrdiff_t... yes
checking for GraphicsMagick++-config... yes
checking for sdl2-config... yes
checking whether byte ordering is bigendian... no
checking for dirent.h that defines DIR... yes
checking for library containing opendir... no
checking for fabs in -lm... no
math library not found
checking for Mix_OpenAudio in -lSDL2_mixer... no
configure: error: *** SDL2_mixer library not found -  ***

But
libsdl2-mixer-dev is already the newest version (2.0.1+dfsg1-1).

I believe this has something to do with changing
-lSDL2_mixer to -lSDL2 or something like that at some point in the configure script, because the API call MixOpenAudio has shifted from one header to another or something? Not sure, just a guess.

But meanwhile, I thought Stellarium360 would work with spherical mirror systems also. Since it won't, then I will pause and rethink my efforts :)
