[Bug]: CANNOT LINK EXECUTABLE "gdalinfo": library "libwebp.so"

[riveryeti]

Problem description

Installing gdal with pkg install gdal after pkg upgrade && pkg update I still get this error:

CANNOT LINK EXECUTABLE "gdalinfo": library "libwebp.so" not found: needed by /data/data/com.termux/files/usr/lib/libgdal.so in namespace (default)

What steps will reproduce the bug?

pkg install gdal gdalinfo --version

What is the expected behavior?

Print gdalinfo version

A workaround is to pkg in libwebp.

For devs: this is so-called automagic dependencies, a common packaging error. In CI, libwebp is pulled in as a dependency of libjxl-progs, a subpackage of libjxl which gdal depends on. So even a single rebuild of gdal in CI makes it depend on libwebp automagically. As gdal does not depend on libjxl-progs either directly or indirectly, it is not pulled in by pkg in gdal.

Adding libwebp to TERMUX_PKG_DEPENDS solved the problem, if updated to the latest version it would encounter build errors.

I think it is possible to link this to solve this problem.

Thanks for the quick fix! Thanks to y'all I was able to build a VRT pointing to a remote cloud-optimized geotiff (COG) all from the comfort of my phone!
