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

These are the steps I took to be able to have lldb breakpoint on a function name in macOS Sierra:

```
cmake . -DCMAKE_BUILD_TYPE=Debug -DTOKUDB_OK=0 -DWITH_LIBARCHIVE=OFF; 
make
cd mysql-test
./mtr --manual-debug 1st
```

This will log a number of parameters, like the path to the mysqld executable and the parameters to pass to it.

# This is the CMakeCache file.
# For build in directory: /Users/ruihpacheco/Desktop/mariadb2
# It was generated by CMake: /opt/local/bin/cmake
# You can edit this file to change values found and used by cmake.
# If you do not want to change any of the values, simply exit the editor.
# If you do want to change a value, simply edit, save, and exit the editor.
# The syntax for the file is as follows:
# KEY:TYPE=VALUE
# KEY is the name of a variable in the cache.
# TYPE is a hint to GUIs for the type of VALUE, DO NOT EDIT TYPE!.
