add a MACRO_DIRECTORY variable to voxels CMakeLists
rename domain target to domain server, use SetupHifiProject
rename MACRO_DIRECTORY variable to MACRO_DIR in voxels lib
move mixer to audio-mixer, use SetupHifiProject macro
use MACRO_DIR variable to find glm in root externals dir
move space to space-server, use setup project macro
move voxel to voxel-server, use setup project macro
some light refactoring in interface CMakeLists
