+## Build system |
|
12 |
+ |
|
13 |
+This project supports [CMake][] and uses [`cmake-common`][]. There are several |
|
14 |
+ways to use it in other CMake-based projects: |
|
15 |
+ |
|
16 |
+- With [`find_package`][]: ([Package][] and) [install][] it on the system. |
|
17 |
+ |
|
18 |
+- With [`add_subdirectory`][]: Bundle it. |
|
19 |
+ |
|
20 |
+- With [`FetchContent`][]: Download it as part of the CMake configure step. |
|
21 |
+ |
|
22 |
+- With [`cmake-common`][]: Use any of the above methods through a simplified |
|
23 |
+ interface. |
|
24 |
+ |
|
25 |
+As usual, use [`add_dependencies`][] or [`target_link_libraries`][] (or |
|
26 |
+`cmake-common`'s `DEPENDENCIES_*`) to declare the dependency. |

+### Configure and generate |
|
39 |
+ |
|
40 |
+To configure and generate a build tree, use `cmake`: |
|
41 |
+ |
|
42 |
+```sh |
|
43 |
+cmake -B _build |
|
44 |
+``` |
|
45 |
+ |
|
46 |
+To set the build type, pass e.g. `-D`[`CMAKE_BUILD_TYPE`][]`=Release`. |
|
47 |
+ |
|
48 |
+[`cmake`]: https://cmake.org/cmake/help/v3.14/manual/cmake.1.html#generate-a-project-buildsystem |
|
49 |
+[`CMAKE_BUILD_TYPE`]: https://cmake.org/cmake/help/v3.14/variable/CMAKE_BUILD_TYPE.html |
|
50 |
+ |
|
51 |
+### Build |
|
52 |
+ |
|
53 |
+To build, use [`cmake --build`][]: |
|
54 |
+ |
|
55 |
+```sh |
|
56 |
+cmake --build _build |
|
57 |
+``` |
|
58 |
+ |
|
59 |
+To disable building tests, pass `-D`[`BUILD_TESTING`][]`=OFF`. |
|
60 |
+ |
|
61 |
+[`cmake --build`]: https://cmake.org/cmake/help/v3.14/manual/cmake.1.html#build-a-project |
|
62 |
+[`BUILD_TESTING`]: https://cmake.org/cmake/help/v3.14/module/CTest.html |
|
63 |
+ |
|
64 |
+### Test |
|
65 |
+ |
|
66 |
+To run tests, use [`ctest`][]: |
|
67 |
+ |
|
68 |
+```sh |
|
69 |
+(cd _build && ctest) |
|
70 |
+``` |
|
71 |
+ |
|
72 |
+To show output from failing tests, pass `--output-on-failure`. To show output |
|
73 |
+from all tests, pass `--verbose`. |

+[`ctest`]: https://cmake.org/cmake/help/v3.14/manual/ctest.1.html |
|
76 |
+ |
|
77 |
+### Package |
|
78 |
+ |
|
79 |
+To package, use [`cpack`][]: |
|
80 |
+ |
|
81 |
+```sh |
|
82 |
+(cd _build && cpack) |
|
83 |
+``` |
|
84 |
+ |
|
85 |
+[`cpack`]: https://cmake.org/cmake/help/v3.14/manual/cpack.1.html |
|
86 |
+ |
|
87 |
+### Install |
|
88 |
+ |
|
89 |
+To install onto the current system, use [`cmake --install`][]: |
|
90 |
+ |
|
91 |
+```sh |
|
92 |
+cmake --install _build |
|
93 |
+``` |
|
94 |
+ |
|
95 |
+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 |
