FindGSL

Finds the native GNU Scientific Library (GSL) includes and libraries:

find_package(GSL [<version>] [...])

The GNU Scientific Library (GSL) is a numerical library for C and C++ programmers. It is free software under the GNU General Public License.

Imported Targets

This module provides the following Imported Targets:

GSL::gsl

Target encapsulating the main GSL library and all usage requirements, available only if GSL is found.

GSL::gslcblas

Target encapsulating the usage requirements of the CBLAS support library used by GSL. This target is available if GSL is found. It is linked also into the GSL::gsl target but provided separately for granularity.

Result Variables

This module defines the following variables:

GSL_FOUND

Boolean indicating whether (the requested version of) GSL was found on the local system.

GSL_VERSION

The version of the discovered GSL installation.

GSL_INCLUDE_DIRS

Directory containing GSL header files.

GSL_LIBRARIES

The GSL libraries.

Cache Variables

This module may set the following variables depending on platform and type of GSL installation discovered. These variables may optionally be set to help this module find the correct files:

GSL_CBLAS_LIBRARY

Location of the GSL CBLAS library.

GSL_CBLAS_LIBRARY_DEBUG

Location of the debug GSL CBLAS library (if any).

GSL_CONFIG_EXECUTABLE

Location of the gsl-config script (if any).

GSL_LIBRARY

Location of the GSL library.

GSL_LIBRARY_DEBUG

Location of the debug GSL library (if any).

Hints

This module accepts the following variables:

GSL_ROOT_DIR

Set this variable to a directory that contains a GSL installation.

If this variable is not set, this module will use pkg-config and default paths to find GSL. If this variable is provided, then this module expects to find libraries at ${GSL_ROOT_DIR}/lib and the GSL headers at ${GSL_ROOT_DIR}/include/gsl.

The library directory may optionally provide Release and Debug folders. If available, the libraries named gsld, gslblasd or cblasd are recognized as debug libraries. For Unix-like systems, this module will also use gsl-config (if found) to aid in the discovery of GSL.

Examples

Finding GSL and linking it to a project target:

find_package(GSL)
target_link_libraries(project_target PRIVATE GSL::gsl)
