Speeding Up Compilation Using Precompiled Headers (PCH), CCache and Ninja in CMake

Abstract

We did some experimentation, and a lot of timing, on how to speed up compile times for C++ projects. In this talk, we are going to discuss:

• Make v.s. Ninja
• Clang v.s. GCC
• The effect of using CCache
• The effect of using Precompiled Headers
• All that using the CMake build system

Some of the material is indeed Linux specific, while others apply just as well on Mac and Windows.
