XO cmake modules

Collects cmake macros to be shared across XO projects (e.g. indentlog, reflect, kalman, ..)

Features

  • support for both manyrepo and monorepo projects
  • support for generating cmake xxxConfig.cmake files, so cmake find_package() works reliably
  • support for header-only libraries
  • support for pybind11 libraries
  • documentation generation using doxygen + breathe + sphinx
  • code coverage using ccov + lcov

Getting Started

copy repo

$ git clone https://github.com:rconybea/xo-cmake.git

configure + install

$ cd xo-cmake
$ cmake -DCMAKE_INSTALL_PREFIX=/usr/local -B .build -S .   # ..or desired prefix
$ cmake --install .build

use from a cmake project

In some project foo:

$ cd foo
$ mkdir cmake
$ cp $PREFIX/share/xo-macros/xo-bootstrap-macros.cmake cmake/

xo-bootstrap-macros-cmake has two vital jobs:

  1. set XO_CMAKE_CONFIG_EXECUTABLE (locate xo-cmake-config)
  2. set CMAKE_MODULE_PATH (obtained from xo-cmake-config --cmake-module-path)

then in foo/CMakeLists.txt:

include(cmake/xo-bootstrap-macros.cmake)

xo_cxx_toplevel_options3()

Now as long as $PREFIX/bin is in PATH:

$ cd mybuild
$ cmake path/to/foo/source

or set XO_CMAKE_CONFIG_EXECUTABLE and CMAKE_MODULE_PATH

In some project foo:

$ cd mybuild
$ cmake -DXO_CMAKE_CONFIG_EXECUTABLE=xo-cmake-config -DCMAKE_MODULE_PATH=$(xo-cmake-config --cmake-module-path) path/to/foo/source
