(macOS Big ) CMake找不到BLAS (失踪: BLAS_LIBRARIES)

Question

我正在尝试在多巢/多聚物上创建macOS；这个程序需要openblas和program作为依赖项。我使用国产软件安装了这两种设备，但是当我试图在MultiNest构建目录中安装cmake时，我会得到以下错误：

CMake Error at /usr/local/Cellar/cmake/3.20.5/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find BLAS (missing: BLAS_LIBRARIES)
Call Stack (most recent call first):
  /usr/local/Cellar/cmake/3.20.5/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:594 (_FPHSA_FAILURE_MESSAGE)
  /usr/local/Cellar/cmake/3.20.5/share/cmake/Modules/FindBLAS.cmake:1045 (find_package_handle_standard_args)
  /usr/local/Cellar/cmake/3.20.5/share/cmake/Modules/FindLAPACK.cmake:265 (find_package)
  /usr/local/Cellar/cmake/3.20.5/share/cmake/Modules/FindLAPACK.cmake:291 (_lapack_find_dependency)
  src/CMakeLists.txt:31 (FIND_PACKAGE)

我已经宣布了很多条路；

export LDFLAGS="-L/usr/local/opt/openblas/lib"
export CPPFLAGS="-I/usr/local/opt/openblas/include"
export PKG_CONFIG_PATH="/usr/local/opt/openblas/lib/pkgconfig"
export LDFLAGS="-L/usr/local/opt/lapack/lib"
export CPPFLAGS="-I/usr/local/opt/lapack/include"
export PKG_CONFIG_PATH="/usr/local/opt/lapack/lib/pkgconfig"

export LD_LIBRARY_PATH=/usr/local/opt/openblas:$LD_LIBRARY_PATH
export BLAS=/usr/local/opt/openblas/lib/libopenblas.a

为什么cmake不能在macOS上找到BLAS？谢谢!

需要将/usr/local/opt/lapack和/usr/local/opt/openblas添加到CMAKE_PREFIX_PATH中，如下所示：

$ cmake -S . -B build -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_PREFIX_PATH="/usr/local/opt/lapack;/usr/local/opt/openblas"

为了避免与苹果自己的Accelerate.framework BLAS实现发生冲突，自制软件不会将它们与Accelerate.framework联系起来。在希伯来语中，这类包装被称为“仅限桶”。

还应该取消设置设置的所有环境变量，因为CMake负责设置包含路径和库路径。
