make_compile_commands.py

# Run this file to make a compile_commands.json file in your project root directory


# The compile_commands.json generated by cmake has info for all binaries but not the header files
# Due to that there might be squiggles in ide while  working with some ides


#  https://pypi.org/project/compdb/
#  This script will use compdb to generate compile_commands.json file
#  which will have header information as well

# Running format : python make_compile_commands.py (<build_directory>)?
