I tried to build the OMCompiler : i cloned the source for the github repository (only the repo of OMCompiler) and followed the readme.linux command

When i launch the first command : autoconf, i have the following error:
/usr/bin/m4:configure.ac:99: cannot open `common/m4/pre-commit.m4': No such file or directory
/usr/bin/m4:configure.ac:101: cannot open `common/m4/ombuilddir.m4': No such file or directory
/usr/bin/m4:configure.ac:255: cannot open `common/m4/ax_cxx_compile_stdcxx_11.m4': No such file or directory
/usr/bin/m4:configure.ac:600: cannot open `common/m4/corba.m4': No such file or directory
/usr/bin/m4:configure.ac:772: cannot open `common/m4/semver.m4': No such file or directory
autom4te: /usr/bin/m4 failed with exit status: 1

I think that the OMCompiler repo and thus OMCompiler could not be compiled alone . Is it a bug ? or am i wrong ?
