The Open Screen library includes its dependencies as DEPS in the source tree under the //third_party/
directory. They are structured as follows:
//third_party/<library> BUILD.gn LICENSE README.chromium ...other necessary adapter files... src/ <library>'s source
When adding a new dependency to the project, you should first add an entry to the DEPS file. For example, let's say we want to add a new library called alpha
. Opening up DEPS, you would add
deps = { ... 'src/third_party/alpha/src': 'https://repo.com/path/to/alpha.git' + '@' + '<revision>'
Then you need to add BUILD.gn
and README.chromium
file for it under //third_party/alpha
, assuming it doesn't already provide its own BUILD.gn
. You will also need to provide a LICENSE
for it if it does not have its own.
You will also need to add a gitmodule entry for the new dependency. Follow the Chromium instructions to synchronize gitmodules with DEPS.
Finally, add a new entry for the src
directory of your dependency to the //third_party/.gitignore
.
Commit all of these changes and upload the CL for review. New dependencies have impacts to binary size, code health, portability, and security so expect some discussion in the review before the new dependency is approved.
