Organizing Git repositories with common nested sub-modules

I'm a big fan of Git sub-modules. I like to be able to track a dependency along with its version, so that you can roll-back to a previous version of your project and have the corresponding version of the dependency to build safely and cleanly. …

So I have been coming across many comments/posts/etc regarding creating makefiles directly, and how it is a silly thing to do in 2015. I am aware of tools such as CMake, and I actually use CMake quite often. The thing is, CMake is just creating the…

In-Source Build vs. Out-Of-Source Build

In my (primarily C++) development, I have long adhered to using out-of-source builds. That is, my source usually sits in a /project/src directory and the builds live in a /project/build/bin/release, /project/build/bin/debug directories. I have…
