It is always a bit annoying to add some GPL-3.0+ code unconditionally
into a package.

But I did a test build of lcms2, and here this plugin is not built:

make[3]: Entering directory '/home/thomas/projets/buildroot/output/build/lcms2-2.10/plugins/fast_float'
make[3]: Nothing to be done for 'all'.
make[3]: Leaving directory '/home/thomas/projets/buildroot/output/build/lcms2-2.10/plugins/fast_float'

Indeed, the top level Makefile.am only recurses into
plugins/fast_float/, which contains a Makefile that does nothing.
plugins/fast_float/src/Makefile.am really does something, but I don't
see it invoked from the top-level build system.

Am I missing something ? Is this fast_float plugin really
built/installed ? If it is, we should make it conditional to not have
GPL-3.0 code added unconditionally along with a MIT-licensed library.

Could you have a look into this ?

Thanks!
