# Gperf recipe. Gperf is only required when building Neovim, when
# cross compiling we still want to build for the HOST system, whenever
# writing a recipe that is meant for cross-compile, use the HOSTDEPS_* variables
# instead of DEPS_* - check the main CMakeLists.txt for a list.
# BuildGperf(CONFIGURE_COMMAND ... BUILD_COMMAND ... INSTALL_COMMAND ...)
# Reusable function to build Gperf, wraps ExternalProject_Add.
# Failing to pass a command argument will result in no command being run
