################################   MAKEFILE OPTIONS     ####################################

# By default, libarchfpga's build type (debug/release) is inherited from VPR's makefile.  
# However, by uncommenting out the line BUILD_TYPE = debug, you can override this 
# and set libarchfpga's build type independently.

# BUILD_TYPE = release

# (can be debug or release)
