Global libvips version does not get detected

I am trying to use the globally installed libvips with sharp, but it does not get detected during the npm install.

Dockerfile:

FROM alpine:3.15
WORKDIR /usr/src/app
RUN apk --update add nodejs=~16 npm build-base vips vips-dev
RUN pkg-config --modversion vips-cpp
RUN npm install --build-from-source --verbose sharp

Relevant parts from the console logs:

...
Step #0: Step 4/8 : RUN pkg-config --modversion vips-cpp
Step #0:  ---> Running in 9b8cfaddb573
Step #0: 8.12.1
...
Step #0: npm info run sharp@0.29.3 install node_modules/sharp (node install/libvips && node install/dll-copy && prebuild-install) || (node install/can-compile && node-gyp rebuild && node install/dll-copy)
Step #0: npm info run sharp@0.29.3 install { code: 0, signal: null }
Step #0: npm timing build:run:install:node_modules/sharp Completed in 19607ms
Step #0: npm timing build:run:install Completed in 19608ms
...

It works if I follow the instructions described in this issue, however, it uses an older version of sharp (0.28.0), alpine (3.14) and node (14).

What could be the reason that the globally installed libvips is not getting detected?

Did you see my comment above?

libvips only supports opening EXR files via the filesystem

Oh, for some reason I read your comment with emphasis on opening (and not writing) instead of on via the filesystem. Okay, this explains everything then. I was looking for the solution at the wrong place all the time. Thank you very much for your help, Lovell.
