CMake

[brendan-nasa]

User simulations keep using plain make. Only building trick now uses cmake. Generated makefiles preserve autotools-built behavior. Autotools (./configure && make) build still works. The cmake build is out-of-tree (conventionally in build/ but can be dev-specified). Out-of-tree builds require patching tools/code/tests that assume builds (TRICK_HOME) are in-tree

Building with cmake

cmake -S . -B build                              # or: cmake --preset default
cmake --build build --target trick_io_src_gen    # runs ICG, writes the io_src list
cmake -S . -B build && cmake --build build       # picks the list up, builds everything
cmake --build build --target stage               # runnable TRICK_HOME in build/stage
ctest --test-dir build -L 'unit|sims'

The three-step bootstrap is only needed on a clean tree (see cmake/TrickICG.cmake); afterwards plain cmake --build build rebuilds incrementally, including re-running ICG when headers change.

Roadmap

• cmake -S. -Bbuild checks match ./configure
• cmake -S. -Bbuild generates equivalent share/trick/makefiles/config_user.mk but out-of-tree
• cmake --build build builds trick-ICG and all nine trick archives matching make
• a working cmake --install build (install into a specific prefix)
• make test -> ctest
• builds all java jars, data products, and civet web
• ci runs that only use cmake
• HDF5 support
• GSL support
• installation documentation
• development documentation

Future work

• remove autotools tooling
• switch CI completely over to cmake
