Meson build system skill for C/C++ projects. Use when setting up a Meson project, configuring build options, managing dependencies with the wrap system, cross-compiling, or integrating Meson with CI. Activates on queries about meson setup, meson compile, meson wrap, meson test, cross-file, meson.bui

Meson Purpose Guide agents through Meson project setup, build configuration, the wrap dependency system, and cross compilation — covering the build system used by GLib, systemd, GStreamer, Mesa, and many major C/C++ projects. Triggers "How do I set up a Meson build?" "How do I add a dependency in Meson?" "How do I cross compile with Meson?" "Meson wrap isn't finding my dependency" "How do I configure build options in Meson?" "How do I migrate from CMake/Autotools to Meson?" Workflow 1. Project setup buildtype Equivalent flags debug (default) O0 g debugoptimized O2 g release O3 DNDEBUG minsize Os DNDEBUG plain No flags added 2. Build and test 3. meson.build structure 4. Dependency management with wrap In meson.build : subprojects/zlib.wrap structure: 5. Build options Define in meson options.txt (or meson.options in Meson ≥1.1): Use in meson.build : 6. Cross compilation Create a cross file ( cross/arm linux.ini ): 7. CMake migration cheatsheet CMake Meson equivalent add executable executable() add library library() / static library() / shared library() target include directories include directories arg in target target link libraries dependencies / link with find package dependency() option() option() in meson options.txt add subdirectory subdir() install(TARGETS ...) install : true in target For wrap patterns and subproject configuration, see [references/meson wrap.md](references/meson wrap.md).
