Conan.io recipe for openblas.

The package is usually consumed using the conan install command or a conanfile.txt. Note This recipe is handcrafted to compile OpenBLAS on Windows with LAPACK, with native support for MSVC. It follows instructions given here: OpenBLAS MSVC. Under normal circumstances you should use OpenBLAS recipe on Conan center This recipe is based on the openblas recipe found on conan center.

How to use this package

1. Add remote to conan's package remotes:

   $ conan remote add sintef https://artifactory.smd.sintef.no/artifactory/api/conan/conan-local

2. Using conanfile.txt in your project with cmake

   Add a conanfile.txt to your project. This file describes dependencies and your configuration of choice, e.g.:

   [requires]
   openblas/[>=0.3.15]@sintef/testing
   
   [options]
   openblas:shared=True
   openblas:build_lapack=True
   openblas:dynamic_arch=True
   
   [imports]
   licenses, * -> ./licenses @ folder=True
   
   [generators]
   cmake_paths
   cmake_find_package
   

   Insert into your CMakeLists.txt something like the following lines:

   cmake_minimum_required(VERSION 3.13)
   project(TheProject CXX)
   
   include(${CMAKE_BINARY_DIR}/conan_paths.cmake)
   find_package(OpenBLAS MODULE REQUIRED)
   
   add_executable(the_executor code.cpp)
   target_link_libraries(the_executor OpenBLAS::OpenBLAS)

   Then, do

   $ mkdir build && cd build
   $ conan install .. -s build_type=<build_type>

   where <build_type> is e.g. Debug or Release. You can now continue with the usual dance with cmake commands for configuration and compilation. For details on how to use conan, please consult Conan.io docs
