Sometimes you need to integrate Nginx build into a larger project. If that project uses CMake, you have two options. Either try to wrap native Nginx build system using ExternalProject_Add(), or to rewrite build steps in CMake language.
Former is easier at start, but you lose control over that build part. Incremental builds become fragile, as CMake dependency extractor is not working for external projects.
Latter is a lot harder, but what you get is uniform build scripts, all in CMake. It's more reliable, and produces way less of clutter on a screen during build.
This repository contains solution in the second way. Scripts in CMake. There are:
- (outdated) direct rewrite of Nginx's build system in /direct-rewrite;
- tracing script approach in /tracing-script.
Direct rewrite was a first attempt to make a CMake build script by manually reimplementing Nginx's build scripts. It targeted Nginx 1.11.6 and Linux, with other OS support dropped right away. That script most probably won't work for other Nginx versions, and definitely won't work on an OS other than GNU/Linux. There is also no dynamic modules support code.
Tracing script is a hack that by intercepting compiler (CC and CXX
variables) learns what files to compile and what objects and libraries
to link. There are more detailed explanations inside the script.
