FindGSL

Added in version 3.2.

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

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

If GSL is found, this module defines the following Imported Targets:

GSL::gsl

The main GSL library that provides all usage requirements to use GSL.

GSL::gslcblas

The CBLAS support library used by GSL. It is linked also into the GSL::gsl target but provided separately for granularity.

Result Variables

This module will set the following variables in the project:

GSL_FOUND

True if GSL is found on the local system.

GSL_INCLUDE_DIRS

Directory containing GSL header files.

GSL_LIBRARIES

The GSL libraries.

GSL_VERSION

The version of the discovered GSL installation.

Hints

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.

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).

Examples

Finding GSL and linking it to a project target:

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