Another project https://github.com/giaf/hpipm that uses blasfeo fails with missing symbols:

Thanks for reporting the issues, the first should have been fixed in the master already when you opened the issue, while the second is now fixed in this commit https://github.com/giaf/blasfeo/commit/4af6c64527344651da1de35511502f970fa3e97e
