[libwebp] do not include all feature by default

[kiwixz]

Currently vcpkg install libwebp will try to install these packages:

  * freeglut[core]:x64-windows
  * giflib[core]:x64-windows
  * libjpeg-turbo[core]:x64-windows
  * liblzma[core]:x64-windows
  * libpng[core]:x64-windows
    libwebp[all,core]:x64-windows
  * opengl[core]:x64-windows
  * sdl1[core]:x64-windows
  * tiff[core]:x64-windows
  * zlib[core]:x64-windows

I dont think that a reasonable default. If a user really wants everything, he should install libwebp[all].

There were many problems with the “bare” port, that’s why I made “all” the default feature. At the same time, having the option to reduce building was very interesting to expose.

Hi @kiwixz, Please also update the CONTROL version. Thanks. I notice that it is 1.0.2-1 now and you can modify it as 1.0.2-2.

@NancyLi1013 thanks, it is done now

@kiwixz @Rastaban The freeimage library fails to build after this update. Seems that webp/mux.h is missing.
Any ideas?

#5886 (comment)

I cannot fully remember the details. But again, I tried saying “please check, together with @vicroms we were not crazy in that PR one month ago...”

[kiwixz]

@theoractice It looks like libwebp's CMakeLists.txt does not install this header when not building gif2webp/img2webp (and consequently libwebpmux), see https://github.com/webmproject/libwebp/blob/1.0.2/CMakeLists.txt#L396.

If that's sufficient to fix subsequent problems, it would probably be better to just force every headers to be installed, imo.

@theoractice freeimage was fixed in #5969

Got it, thank you all.
