| # wolfTPM links wolfSSL/wolfCrypt (RNG, parameter encryption, PK | |
| # callbacks), so its SBOM records wolfSSL as a dependency. wolfSSL is | |
| # built + installed here so wolfTPM has a library to link, and the same | |
| # source tree (scripts/gen-sbom + wolfssl/version.h) is passed to | |
| # `make sbom` via WOLFSSL_DIR -- so the recorded wolfSSL dependency | |
| # version matches the linked one. gen-sbom is not yet on wolfssl master, | |
| # so default to the open PR head that carries it (wolfSSL/wolfssl#10343) | |
| # so CI actually exercises `make sbom` instead of silently skipping. | |
| # TODO: switch the fallback back to 'master' once #10343 merges. | |
