Mesen/makefile

#Welcome to what must be the most terrible makefile ever (but hey, it works)
#Both clang & gcc work fine - clang seems to output faster code
#The only external dependency is SDL2 - everything else is pretty standard.
#Run "make" to build, "make run" to run

#----------------------
#Platform Configuration
#----------------------
#To specify whether you want to build for x86 or x64:
#"MESENPLATFORM=x86 make" or "MESENPLATFORM=x64 make"
#Default is x64

#-----------------------
# Link Time Optimization
#-----------------------
#LTO is supported for clang only
#LTO gives a 25-30% performance boost, so use it whenever you can
#Usage: LTO=true make
