Why I get error message in R2019a: Undefined function "xmakefilesetup"

For the configuration of the makefile-generation-tool we use the xmakefilesetup-function. In the newer Matlab versions I am getting the error message "Undefined function xmakefilesetup".  And if I check the usual directory of the function, I could not find it \MATLAB\R2019a\toolbox\idelink\foundation\xmakefile.

Can you help please?

The file "xmakefilesetup" was removed as of R2018b. The old documentation page also mentioned this change, run the following command in MATLAB R2018a-

web(fullfile(docroot, 'ecoder/ug/makefiles.html'))

The XMakefile feature is an older build process that uses extended template makefiles. You should now use the toolchain approach build process, please refer to the following documentation page for R2019a:
