[cmake-developers] Is there an official FindMKL module?

[Tim Gallagher]

We sometime struggled to get it working, but we never had to resort to using a FindMKL -- FindBLAS and FindLAPACK work just fine for us, provided we do things "correctly." 

So long as we have sourced the mklvars script that ships with Intel MKL and we put: 

BLA_VENDOR =Intel10_64lp_seq ccmake /path/to/source/dir 
Then everything works fine and we have no issues. So we have to give CMake a hint that we want to pick the Intel version rather than the generic one (and we're using the sequential, 64bit MKL -- if you look in FindBLAS you can see other vendor types). 

Have you had things fail when you setup your environment variables using the scripts Intel provides and when you set the BLA_VENDOR hint as an environment variable?

Hello, 


I am using the find_package() command to load settings for the Intel Math Kernel Library (MKL). This works through a custom FindMKL.cmake module that I've made for myself. 


However, when looking at: 
https://software.intel.com/en-us/articles/intel-mkl-link-line-advisor/ 

I can tell that what I've done is likely only correct for my specific case, and certainly not robust against library version changes and various other changes (openmp, static vs dynamic linking etc.). 



Instead of a FindMKL.cmake module, an alternative is to have MKL be discovered in the FindBLAS or FindLAPACK modules, but according to what I can find on the bug tracker, that solution is also in a fairly broken state: 

Bug 14138: http://www.cmake.org/Bug/view.php?id=14138 

Bug 13543: http://www.cmake.org/Bug/view.php?id=13543 

Bug 13528: http://www.cmake.org/Bug/view.php?id=13528 



Google tells me that many people have (like me) created their own FindMKL.cmake module, which are equally specific and tailored. 



Is anyone aware of a more "official" FindMKL module available somewhere, or at least something that is being somewhat maintained, either by someone at Kitware or Intel? Or of a plan to develop something like that? 



kind regards,
