FindGnuplot¶

Finds the Gnuplot command-line graphing utility for generating two- and three-dimensional plots (gnuplot):

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

Result Variables¶

This module defines the following variables:

Gnuplot_FOUND: Boolean indicating whether (the requested version of) Gnuplot has been found. For backward compatibility, the GNUPLOT_FOUND variable is also set to the same value.
Gnuplot_VERSION: Added in version 4.2.

The version of Gnuplot found.

Note

Version detection is available only for Gnuplot 4 and later. Earlier versions did not provide version output.

Cache Variables¶

The following cache variables may also be set:

GNUPLOT_EXECUTABLE: Absolute path to the gnuplot executable.

Deprecated Variables¶

The following variables are provided for backward compatibility:

GNUPLOT_VERSION_STRING: Deprecated since version 4.2: Superseded by the Gnuplot_VERSION.

The version of Gnuplot found.

Examples¶

Finding Gnuplot and executing it in a process:

find_package(Gnuplot)
if(Gnuplot_FOUND)
  execute_process(COMMAND ${GNUPLOT_EXECUTABLE} --help)
endif()
