* Find{BLAS,LAPACK}: Avoid clobbering results when no vendor is requestedBrad King2021-07-121-2/+2
| | | | | | | | | | | | Logic added by commit 4c74c86f40 (FindBLAS/LAPACK: Add support for the Fujitsu SSL2 library, 2021-01-27, v3.21.0-rc1~402^2~1) accidentally expressed a boolean condition without proper grouping. The pattern was then copied by commit 2c9e623e31 (Find{BLAS,LAPACK}: Add support for the NVHPC LAPACK library, 2021-05-05, v3.21.0-rc1~192^2). The resulting logic incorrectly tries Fujitsu and NVHPC vendors even after results are found from another vendor, and then erases those. Fix the grouping. Fixes: #22403

* FindBLAS: Revert "Do not statically link against iomp5 ... Intel MKL"Brad King2021-06-101-16/+7
| | | | | | | | | | Since commit 20ab504591 (FindBLAS: Do not statically link against iomp5 in the case of Intel MKL, 2021-04-11), we no longer find MKL's BLAS when using the GNU compiler because FindOpenMP chooses libgomp instead of libiomp5, and mkl_intel_thread depends on the latter. Revert the change for now. A new approach will be needed to solve the original problem. Issue: #21811

* Find{BLAS,LAPACK}: Simplify search for static librariesBrad King2021-04-211-19/+13
| | | | | | | | Now that `CHECK_{BLAS,LAPACK}_LIBRARIES` are functions, we can set `CMAKE_FIND_LIBRARY_SUFFIXES` locally without affecting the global state. This avoids the need for local state switching that was added in commit 9ef82d95d8 (FindBLAS: Fix detection of OpenMP as dependency of BLA_STATIC, 2021-04-07, v3.20.1~3^2), so remove that.

* Find{BLAS,LAPACK}: Revert bad refactoring of internal CHECK_*_LIBRARIESBrad King2021-04-141-7/+9
| | | | | | | | | | | | | | | | | | | Refactoring in commit 4c74c86f40 (FindBLAS/LAPACK: Add support for the Fujitsu SSL2 library, 2021-01-27) was done in order to support calling `find_library` on the dependencies as well as the candidate libraries. However, it broke a few things: * Intel MKL's BLAS/LAPACK are no longer found. We specify their dependencies using `-l...` flags, so we should not try to use `find_library` for them. * The dependencies are repeated because we accumulate them in the `find_library` search loop and then append them at the end too. Revert the incorrect part of the refactoring. Retain the flags part needed for the Fujitsu vendor. Fixes: #22056

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the change from commit f7f3d8987a (FindBLAS: Add dependency of OpenBLAS on OpenMP for BLA_STATIC, 2020-11-10, v3.20.0-rc1~492^2): * If C is not enabled, find CXX OpenMP libraries instead. * Do not use BLA_STATIC's custom CMAKE_FIND_LIBRARY_SUFFIXES for OpenMP. It can break projects that already call `find_package(OpenMP)` and expect a shared library. Whether OpenMP is static is orthogonal to whether BLAS is static. Fixes: #22039 Issue: #16221

* | Find{BLAS,LAPACK}: Add missing thread library for Intel MKL on Win32evatux2020-06-231-1/+5
| | | | | | | | | | | | | | | | | | The patch also updates the documentation to explicitly state that Intel10_32 stands for threaded case (linked with Intel OpenMP). Later, one may need to add Intel10_32_seq to support linking with the sequential version of Intel MKL. Fixes: #20857
* | FindBLAS: Extend search directories for MKLevatux2020-06-161-0/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | Even though Intel MKL typically puts the libraries under `$MKLROOT/lib/$arch_$os` some installations may still use `$MKLROOT/lib/$arch/` path. Ideally, `$arch` should be a symlink to `$arch_$os`, but sometimes the opposite happens (for instance, see Intel MKL distribution in Arch Linux [1]), and sometimes only `$arch` directory alone is present. This patch extends the search list with `$MKLROOT/lib/$arch` with lower priority than `$MKLROOT/lib/$arch_$os`, as the latter is the official path to Intel MKL libraries. It is also worth mentioning that Intel MKL Link Line Adviser [2] recommends using `$MKLROOT/lib/$arch` directory in a link line: ``` -L${MKLROOT}/lib/intel64 -Wl,--no-as-needed -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lpthread -lm -ldl ``` [1] https://www.archlinux.org/packages/community/x86_64/intel-mkl/files/ [2] https://software.intel.com/content/www/us/en/develop/articles/intel-mkl-link-line-advisor.html

* Find{BLAS,LAPACK}: Include parent of points directory in searchMario Emmenlauer2020-01-311-0/+7
| | | | | | | This is required if MKLROOT points to the subdirectory .../mkl/ instead of the root of an Intel MKL library installation. Only in this case the MKL will be searched starting from the parent directory, to detect relevant dependencies in parallel subdirectories, like 'compiler' and 'tbb'.

* Find{BLAS,LAPACK}: Search always in dynamic linker pathsMario Emmenlauer2020-01-281-8/+6
| | | | | | | | | Previously the search in the dynamic linker paths 'LIB', 'LD_LIBRARY_PATH' and 'DYLD_LIBRARY_PATH' was dependent on the value of the environment variable 'MKLROOT'. If MKLROOT was given, the dynamic linker paths where not searched. This seems slightly counter-intuitive. This PR changes the behavior so that MKLROOT is searched first, but if unsuccesful, the dynamic linker paths are tried as well.

| | | | | | | | | | Bring whitespace and code style up to date in these scripts. Both scripts share the same origin but have diverged over time, so synchronize them again. This is relevant because BLAS and LAPACK detection is often performed simultaneously, so both scripts should evolve in sync. While at it, update a few comments. This update is intended to have no functional changes.
