Hello John,

Good guess, then I took some times to dig in my logs:

The configuration script had found BrotliDec in MacPorts folders: /opt/local.
However I take care to keep away MacPorts when building GTK-OSX. 

How to prevent the search in /opt/local?

Looking at CMakeLists.txt, even Brotli is set off, it is looked for (line 90):
#                    -D CMAKE_DISABLE_FIND_PACKAGE_BrotliDec=TRUE [...]

Or else is it possible to add this option?

Thanks, Pascal.
