# Info:
# This makefile is gnu-make spacific, other make systems needn't understand it
# This makefile generates include-file dependencies into *.d files in each build and then reuses these dependencies in the following builds
#
# Usage:
# To make a release build, call "make"
# To make a debug build, call "make debug=1"

# CC_OPTIONS ... options for the C code compiler

# LNK_OPTIONS ... options for the linker
# LNK_LIBS ... libraries to link in
# -- according to https://stackoverflow.com/questions/6183899/undefined-reference-to-dlopen, libs must come after all sources
