Note about CFLAGS & LDFLAGS
This may be helpful when you get errors during compiling source codes.
CFLAGS as environment variable sets PATH to include directory
LDFLAGS as environment variable sets PATH to lib directory
For example, adding another openssl from Homebrew to compile something:
CFLAGS="-I$(brew --prefix openssl)/include" LDFLAGS="-L$(brew --prefix openssl)/lib" make
This make you use specified openssl to make
