-D CMAKE_BUILD_TYPE=type      # type = Release or Debug

-G output                     # style of output CMake generates

-DVARIABLE=value              # setting for a LAMMPS feature to enable

-D VARIABLE=value             # ditto, but cannot come after CMakeLists.txt dir :pre

-D VARIABLE=value             # ditto, but cannot come after CMakeLists.txt dir

-C path/to/preset/file        # load some CMake settings before configuring :pre

All the LAMMPS-specific -D variables that a LAMMPS build supports are

described on the pages linked to from the "Build"_Build.html doc page.

cmake -C ../cmake/presets/all_on.cmake \[OPTIONS\] ../cmake  | enable all packages

cmake -C ../cmake/presets/all_off.cmake \[OPTIONS\] ../cmake | disable all packages

cmake -C ../cmake/presets/std.cmake \[OPTIONS\] ../cmake | enable standard packages

cmake -C ../cmake/presets/user.cmake \[OPTIONS\] ../cmake | enable user packages

cmake -C ../cmake/presets/std_nolib.cmake \[OPTIONS\] ../cmake | enable standard packages that do not require extra libraries

cmake -C ../cmake/presets/nolib.cmake \[OPTIONS\] ../cmake | disable all packages that do not require extra libraries

cmake -C ../cmake/presets/manual_selection.cmake \[OPTIONS\] ../cmake | example of how to create a manual selection of packages :tb(s=|,a=l)

cmake -C ../cmake/presets/minimal.cmake \[OPTIONS\] ../cmake | enable just a few core packages

cmake -C ../cmake/presets/most.cmake \[OPTIONS\] ../cmake | enable most common packages

cmake -C ../cmake/presets/nolib.cmake \[OPTIONS\] ../cmake | disable packages that do require extra libraries or tools

cmake -C ../cmake/presets/mingw.cmake \[OPTIONS\] ../cmake | enable all packages compatible with MinGW (cross-)compilation on Windows :tb(s=|,a=l)s

NOTE: Running cmake this way manipulates the variable cache in your

current build directory. You can combine presets and options with

multiple cmake runs.

[Example:]

# build LAMMPS with all "standard" packages which don't

# use libraries and enable GPU package

# build LAMMPS with most commonly used packages, but then remove

# those requiring additional library or tools, but still enable

# GPU package and configure it for using CUDA. You can run.

mkdir build

cd build

cmake -C ../cmake/presets/std_nolib.cmake -D PKG_GPU=on ../cmake :pre

cmake -C ../cmake/presets/most.cmake -C ../cmake/presets/nolib.cmake -D PKG_GPU=on -D GPU_API=cuda ../cmake :pre

# to add another package, say BODY to the previous configuration you can run:

cmake -D PKG_BODY=on . :pre

# to reset the package selection from above to the default of no packages

# but leaving all other settings untouched. You can run:

cmake -C ../cmake/presets/no_all.cmake . :pre
