Try to find GNU gperf.

If the gperf executable is not in your PATH, you can provide an alternative name or full path location with the Gperf_EXECUTABLE variable.

This will define the following variables:


True if gperf is available.


The gperf executable.

If Gperf_FOUND is TRUE, it will also define the following imported target:


The gperf executable.

and the following public function:

ecm_gperf_generate(<GperfInput> <OutputFile> <OutputVariable>


Run gperf on <GperfInput> to generate <OutputFile>, adding it to the <OutputVariable> variable which contains the source for the target where <OutputFile> is going to be built. The optional GENERATION_FLAGS argument is needed to pass extra parameters to gperf (note you cannot override that way the output file).

A simple invocation would be:

ecm_gperf_generate(simple.gperf ${CMAKE_CURRENT_BINARY_DIR}/simple.h MySources)

Since 5.35.0.
