Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

Music searching

This gist contains some tools I wrote to solve a problem I ran into when archiving folk tunes. Once I had 30+ tunes in the archive, it became hard to tell whether any particular tune I came across was already in the archive or not, and I'm usually not able to remember a tune note-for-note. The solution to this problem was to build a tool that could search for music scores based on an approximately-similar snippet.

Details

These tools are tuned to my particular setup, but the core should be generalizable. Here are the assumptions the code makes:

Scores are stored as compressed MusicXML (.mxl) files
The scores and both scripts are stored in the same directory

Installing ndctl, pmdk and ipmctl:

Keep the installation directories around for both of these libs, as the only way to uninstall them is by going into the original install dirs, and then make uninstall.

Required for both ndctl and pmdk:

$ apt install pkg-config
$ export PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig:/lib/x86_64-linux-gnu/pkgconfig:/usr/lib/pkgconfig:${PKG_CONFIG_PATH}
