| Find neural-fortran | ||
| ------------------- | ||
| Makes the neural-fortran library project available. | ||
| Imported Targets | ||
| ^^^^^^^^^^^^^^^^ | ||
| This module provides the following imported target, if found: | ||
| ``neural-fortran::neural-fortran`` | ||
| The neural-fortran library | ||
| Result Variables | ||
| ^^^^^^^^^^^^^^^^ | ||
| This module will define the following variables: | ||
| ``NEURAL-FORTRAN_FOUND`` | ||
| True if the neural-fortran library is available | ||
| ``NEURAL-FORTRAN_SOURCE_DIR`` | ||
| Path to the source directory of the neural-fortran library project, | ||
| only set if the project is included as source. | ||
| ``NEURAL-FORTRAN_BINARY_DIR`` | ||
| Path to the binary directory of the neural-fortran library project, | ||
| only set if the project is included as source. | ||
| Cache variables | ||
| ^^^^^^^^^^^^^^^ | ||
| The following cache variables may be set to influence the library detection: | ||
| ``NEURAL-FORTRAN_FIND_METHOD`` | ||
| Methods to find or make the project available. Available methods are | ||
| - ``cmake``: Try to find via CMake config file | ||
| - ``pkgconf``: Try to find via pkg-config file | ||
| - ``subproject``: Use source in subprojects directory | ||
| - ``fetch``: Fetch the source from upstream | ||
| ``NEURAL-FORTRAN_DIR`` | ||
| Used for searching the CMake config file | ||
| ``NEURAL-FORTRAN_SUBPROJECT`` | ||
| Directory to find the neural-fortran library subproject, relative to the project root | ||
