Making a portfile from a cmake based project

OK.
Added a github.tarball_from releases command as there is a release on
github.
Nevertheless, I had to manually add the  libebur128-1.1.0.tar.gz file into
the /opt/local/var/macports/distfiles/libebur128 directory to have the
installation work, otherwise `port` was searching for the archive in it's
usual online repositories. Is that the expected behavior ?

Then use "sudo port -v extract" to get the checksums (disclaimer:

OK

Now, if I add the following lines to the Portfile (at the end)

variant with_tests description {Build tests suite} {
  configure.args-append -DENABLE_TESTS=ON
}

and run

port variants libebur128

the result is :

libebur128 has the variants:
   debug: Enable debug binaries
   universal: Build for multiple architectures

So it seems that my with_tests variant is not found.
I have tried a portindex command in the ~/ports directory with no success.
