#The scrypt library does not use a config.h, so we must introduce a number
#of -D arguments instead of generating a config.h. The right thing to do would
#be to introduce a config.h, but that would require modifying all source files
#by adding include(config.h). We would rather avoid that and keep all
#modifications in this drop-in CMakeLists.txt file.
