guru/dev-libs/lsquic/files/lsquic-link-boringssl-static-libs-9fc1c.patch

Modify the BoringSSL library to be included internally during LSQUIC construction, so that the BoringSSL library does not need to be installed by itself on the system.
BoringSSL must always be built as static, so we intentionally removed the code that builds it as shared.
