makemake

A shell script suitable for generating a C++ cmake-compatible CMakeLists.txt file which then creates a Makefile for the make command

Overview

If you're attempting to use the command line tools to build C++ files for ANSI-compatible purposes, you'll find that there are a number of steps involved.

In order to run the make command, you first need a Makefile in the project folder which describes what to build. Researching, you see that cmake shoud do this for you...
In order to create a Makefile, cmake first wants you to create a CMakeList.txt in the project folder. But now you'd need to research that format.

What this script does

This script is meant to scaffold the current folder so that it's make-ready for simple C++ projects.

Assumptions

All *.cpp files are compiled together to create the executable
The name of the executable is the lowercase version of the project folder's name itself (and the project name doesn't include any space characters)
Your system runs shell scripts
You have make and cmake in your path (brew install cmake is perhaps the easiest way to get that second one)

How to use

Place the makemake script somewhere in your PATH. I put mine in ~/local/scripts which is in my path. Make sure that the script is marked so that it can execute: chmod a+x makemake

Finally, in the project folder itself, run makemake.

What it does

Generates a CMakeLists.txt file in the current directory
Runs cmake . -G"Unix Makefiles" in the current directory
Runs make in the current directory

What's next?

Assuming that the executable works, the standard workflow then is simply:

Edit a *.cpp file, saving it
Run make in the project folder
