    Use Sourcetrail with ROS

1. Build your workspace with the required cmake flag

Building your workspace with -DCMAKE_EXPORT_COMPILE_COMMANDS=ON which will create a file compile_commands.json in your build/<pkg> directory containing all compiler calls.
colcon build --cmake-args -DCMAKE_EXPORT_COMPILE_COMMANDS=ON

2. Add the project to sourcetrail

See images below

```
cmake src/<package_name>/ --graphviz=foo.dot
xdot foo.dot
```
Set options for better exclude by adding a file src/<package_name>/CMakeGraphVizOptions.cmake with
```
set(GRAPHVIZ_EXTERNAL_LIBS FALSE)
set(GRAPHVIZ_IGNORE_TARGETS "gtest;gmock;unittest*;integrationtest*")
```
