## CMake subprojects
|
||
|
|
|
||
|
|
Meson can now directly consume CMake based subprojects. Using CMake
|
||
|
|
subprojects is almost identical to using the "normal" meson subprojects:
|
||
|
|
|
||
|
|
```meson
|
||
|
|
sub_proj = subproject('libsimple_cmake', method : 'cmake')
|
||
|
|
```
|
||
|
|
|
||
|
|
The `method` key is optional if the subproject only has a `CMakeList.txt`.
|
||
|
|
Without specifying a method meson will always first try to find and use a
|
||
|
|
`meson.build` in the subproject.
|
||
|
|
|
||
|
|
Project specific CMake options can be added with the new `cmake_options` key.
|
||
|
|
|
||
|
|
The returned `sub_proj` supports the same options as a "normal" subproject.
|
||
|
|
Meson automatically detects build targets, which can be retrieved with
|
||
|
|
`get_variable`. Meson also generates a dependency object for each target.
|
||
|
|
|
||
|
|
These variable names are generated based on the CMake target name.
|
||
|
|
|
||
|
|
```cmake
|
||
|
|
add_library(cm_exe SHARED ${SOURCES})
|
||
|
|
```
|
||
|
|
|
||
|
|
For `cm_exe`, meson will then define the following variables:
|
||
|
|
|
||
|
|
- `cm_exe` The raw library target (similar to `cm_exe = library('cm_exe', ...)` in meson)
|
||
|
|
- `cm_exe_dep` The dependency object for the target (similar to `declare_dependency()` in meson)
|
||
|
|
- `cm_exe_inc` A meson include directory object, containing all include irectories of the target.
|
||
|
|
|
||
|
|
It should be noted that not all projects are guaranteed to work. The
|
||
|
|
safest approach would still be to create a `meson.build` for the
|
||
|
|
subprojects in question.
