## Build system
This project supports [CMake][] and uses [`cmake-common`][]. There are several
ways to use it in other CMake-based projects:
- With [`find_package`][]: ([Package][] and) [install][] it on the system.
- With [`add_subdirectory`][]: Bundle it.
- With [`FetchContent`][]: Download it as part of the CMake configure step.
- With [`cmake-common`][]: Use any of the above methods through a simplified
interface.
As usual, use [`add_dependencies`][] or [`target_link_libraries`][] (or
`cmake-common`'s `DEPENDENCIES_*`) to declare the dependency.
[CMake]: https://cmake.org
[`cmake-common`]: https://git.rcrnstn.net/rcrnstn/cmake-common
[`FetchContent`]: https://cmake.org/cmake/help/v3.14/module/FetchContent.html
[`add_subdirectory`]: https://cmake.org/cmake/help/v3.14/command/add_subdirectory.html
[`find_package`]: https://cmake.org/cmake/help/v3.14/command/find_package.html
[Package]: #Package
[Install]: #Install
[`add_dependencies`]: https://cmake.org/cmake/help/v3.14/command/add_dependencies.html
[`target_link_libraries`]: https://cmake.org/cmake/help/v3.14/command/target_link_libraries.html
### Configure and generate
To configure and generate a build tree, use `cmake`:
```sh
cmake -B _build
```
To set the build type, pass e.g. `-D`[`CMAKE_BUILD_TYPE`][]`=Release`.
[`cmake`]: https://cmake.org/cmake/help/v3.14/manual/cmake.1.html#generate-a-project-buildsystem
[`CMAKE_BUILD_TYPE`]: https://cmake.org/cmake/help/v3.14/variable/CMAKE_BUILD_TYPE.html
### Build
To build, use [`cmake --build`][]:
```sh
cmake --build _build
```
To disable building tests, pass `-D`[`BUILD_TESTING`][]`=OFF`.
[`cmake --build`]: https://cmake.org/cmake/help/v3.14/manual/cmake.1.html#build-a-project
[`BUILD_TESTING`]: https://cmake.org/cmake/help/v3.14/module/CTest.html
### Test
To run tests, use [`ctest`][]:
```sh
(cd _build && ctest)
```
To show output from failing tests, pass `--output-on-failure`. To show output
from all tests, pass `--verbose`.
[`ctest`]: https://cmake.org/cmake/help/v3.14/manual/ctest.1.html
### Package
To package, use [`cpack`][]:
```sh
(cd _build && cpack)
```
[`cpack`]: https://cmake.org/cmake/help/v3.14/manual/cpack.1.html
### Install
To install onto the current system, use [`cmake --install`][]:
```sh
cmake --install _build
```
To set the prefix, pass e.g. `-D`[`CMAKE_INSTALL_PREFIX`][]`="$HOME/.local"`.
[`cmake --install`]: https://cmake.org/cmake/help/v3.14/manual/cmake.1.html#install-a-project
[`CMAKE_INSTALL_PREFIX`]: https://cmake.org/cmake/help/v3.14/variable/CMAKE_INSTALL_PREFIX.html
