Makefile template for creating libraries

  git clone https://github.com/mcu/mklib.git
  cd mklib
  make

How to use

delete 'img' folder and 'README.md' file to cleanup template;
rename folder 'mkdir';
replace 'lwip' folder with your own source code;
set path to C compiler directory (makefile variable CCDIR);
specify a processor (makefile variable CORE);
change other variables if needed;
'make build' > fix > 'make clean' until your source code compiles successfully into library.
