ERROR: Failed finding all of the parts of TPL 'BLAS' with Trilinos when OpenBLAS is there on RHEL 8

[SomePersonSomeWhereInTheWorld]

I know I've seen mention of creating sym links to openblas to blas but is that still needed?

-- Searching for libs in BLAS_LIBRARY_DIRS='/path/to/openblas/0.3.7/lib'
-- Searching for a lib in the set "blas blas_win32":

-- NOTE: Did not find a lib in the lib set "blas blas_win32" for the TPL 'BLAS'!
-- ERROR: Could not find the libraries for the TPL 'BLAS'!
-- TIP: If the TPL 'BLAS' is on your system then you can set:
     -DBLAS_LIBRARY_DIRS='<dir0>;<dir1>;...'
   to point to the directories where these libraries may be found.
   Or, just set:
     -DTPL_BLAS_LIBRARIES='<path-to-libs0>;<path-to-libs1>;...'
   to point to the full paths for the libraries which will
   bypass any search for libraries and these libraries will be used without
   question in the build.  (But this will result in a build-time error
   if not all of the necessary symbols are found.)
-- ERROR: Failed finding all of the parts of TPL 'BLAS' (see above), Aborting!

-- NOTE: The find module file for this failed TPL 'BLAS' is:
     /path/to/candi/9.4.2-r3/tmp/unpack/Trilinos-trilinos-release-13-2-0/cmake/tribits/common_tpls/FindTPLBLAS.cmake
   which is pointed to in the file:
     /path/to/candi/9.4.2-r3/tmp/unpack/Trilinos-trilinos-release-13-2-0/TPLsList.cmake

TIP: One way to get past the configure failure for the
TPL 'BLAS' is to simply disable it with:
  -DTPL_ENABLE_BLAS=OFF
which will disable it and will recursively disable all of the
downstream packages that have required dependencies on it, including
the package 'TeuchosNumerics' which triggered its enable.
When you reconfigure, just grep the cmake stdout for 'BLAS'
and then follow the disables that occur as a result to see what impact
this TPL disable has on the configuration of Trilinos.

Edit: same error as in this discussion but we don't have IKL installed.

Even I faced the same issue. I was able to overcome it by installing the openblas using candi. Hope it works for you too.

Indeed in candi.cfg I put:
PACKAGES="${PACKAGES} once:openblas"

Got it to compile. Thanks.
