| # FindAccelerateSparse.cmake - Find the sparse solvers in Apple's Accelerate |
| # framework, introduced in Xcode 9.0 (2017). |
| # Note that this is distinct from the Accelerate |
| # framework on its own, which existed in previous |
| # versions but without the sparse solvers. |
| # |
| # This module defines the following variables which should be referenced |
| # by the caller to use the library. |
| # |
| # AccelerateSparse_FOUND: TRUE iff an Accelerate framework including the sparse |
| # solvers, and all dependencies, has been found. |
| # AccelerateSparse_INCLUDE_DIRS: Include directories for Accelerate framework. |
| # AccelerateSparse_LIBRARIES: Libraries for Accelerate framework and all |
| # dependencies. |
| # |
| # The following variables are also defined by this module, but in line with |
| # CMake recommended FindPackage() module style should NOT be referenced directly |
| # by callers (use the plural variables detailed above instead). These variables |
| # do however affect the behaviour of the module via FIND_[PATH/LIBRARY]() which |
| # are NOT re-called (i.e. search for library is not repeated) if these variables |
| # are set with valid values _in the CMake cache_. This means that if these |
| # variables are set directly in the cache, either by the user in the CMake GUI, |
| # or by the user passing -DVAR=VALUE directives to CMake when called (which |
| # explicitly defines a cache variable), then they will be used verbatim, |
| # bypassing the HINTS variables and other hard-coded search locations. |
| # |
| # AccelerateSparse_INCLUDE_DIR: Include directory for Accelerate framework, not |
| # including the include directory of any |
| # dependencies. |
| # AccelerateSparse_LIBRARY: Accelerate framework, not including the libraries of |
| # any dependencies. |
| |
| # Called if we failed to find the Accelerate framework with the sparse solvers. |
| # Unsets all public (designed to be used externally) variables and reports |
| # error message at priority depending upon [REQUIRED/QUIET/<NONE>] argument. |
