Emscripten - duplicate symbols between ofxOpenCV and FreeImage libs

Now that addon libraries are linking again new issue popped up:

maybe WITH_PNG=OFF ?
by the way take a look at this kind of selectors, all CMAKE options in one place, and exceptions made by platform

[ofTheo]

Thanks @dimitre !
I'll try that!

And yeah the chalet.yaml looks very tidy :)

@ofTheo -DWITH_OPENJPEG=OFF \

[danoli3]

@ofTheo this is fixed now yeah
