|
|
$ mkdir ccov
|
|
$ cd ccov

## Development
|
|
|
|
### LSP support
|
|
|
|
LSP looks for compile commands in the root of the source tree;
|
|
cmake creates them in the root of its build directory.
|
|
|
|
```
|
|
$ cd xo-kalmanfilter
|
|
$ ln -s build/compile_commands.json
|
|
```
|
|
|
|
### display cmake variables
|
|
|
|
- `-L` list variables
|
|
- `-A` include 'advanced' variables
|
|
- `-H` include help text
|
|
|
|
```
|
|
$ cd xo-kalmanfilter/build
|
|
$ cmake -LAH
|
|
```
