Dear developers,
Currently, FindLAPACK.cmake and FindBLAS.cmake *requires* Fortran compiler.
However, I can easily think of a situation when no Fortran compiler
but LAPACK/BLAS
available. Let's say:
* Use ATLAS on VC9 (Windows)
* Buy Intel C++ compiler but not Fortran compiler (each of them have
MKL) (Windows/Linux)
Is there any way to properly detect BLAS/LAPACK with C/C++ only project?
Those with knowledge of the Fortran versions of lapack/blas libraries may
not have similar good knowledge of the C/C++ versions of those libraries and
vice versa. Also, the fortran version find needs may interfere with the C/C++
version find needs and vice versa.
Thus, I think it makes a lot of sense to have separate development of
FindCLAPACK.cmake and FindCBLAS.cmake (note the name change) for the purpose
of dealing with the C/C++ versions of lapack/blas.
Years ago when I started FindLAPACK.cmake and FindBLAS.cmake, I implemented
something really simple that worked for just my needs. After that start,
Alin M Elena (who has a lot more Fortran Lapack/blas expertise than I do)
took over and vastly generalized my work.
CMake is a free software project, and Find modules are completely
straightforward to write if you have the necessary background knowledge
about the libraries involved. Thus, I suggest because of your need to find
C/C++ versions of lapack/blas, that you should write a small
FindCLAPACK.cmake and FindCBLAS.cmake that satisfies your needs, and see
where it leads from there.
