see #12956. The problem is probably openblas and not lapack. lapack just creates a symlink to/copy of openblas.pc file named blas.pc if and only if openblas.pc exists.

This issue should be fixed by PR #12569, could you please ensure your vcpkg is latest?

JackBoosY on 17 Aug 2020

I just had the same issue with the most recent version of vcpkg.

The problem seems to be that OpenBLAS does not install the pkg-config file when pkg-config is not found during configure time. See https://github.com/xianyi/OpenBLAS/blob/efdd237a91646f0ce58815ef6507c04e393813a6/CMakeLists.txt#L392-L396.

I have opened a PR #12956 to address that issue.

Vcpkg is the latest.

The problem is caused by blas.pc file not being installed.

cmake version?

cmake version?

Both 3.17.2 and 3.18.1 have the same error.

Yes, that should be the root cause, openblas.pc file does not exist either.

I have the same problem

Vcpkg version: 2020.06.15-nohash

Please any help?
vcpkg is the latest and there is no problem with openblas.

merge patch #12956
reinstall openblas

merge patch #12956
reinstall openblas

Could you please clarify what do you mean by "merge patch". I am using Windows 10 and running these command on cmd.

Also this is the detail of the problem
