binder: update dependencies

[neteler]

Attempt to update dependencies to fix failing binder sessions.

I tested this in Binder and got the following error:

checking whether to use PDAL... yes
Package geos was not found in the pkg-config search path.
Perhaps you should add the directory containing `geos.pc'
to the PKG_CONFIG_PATH environment variable
Package 'geos', required by 'pdal', not found
configure: error: *** Unable to locate suitable (>=1.7.1) PDAL library.

Thanks for testing. Can you pls check the relevant snippet in config.log to see the real error?

And, would this help (very unusual, though):
export PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig/

I'm not sure how to check that in Binder since the terminal is display-only. Here's a link in case anyone wants to test:

Maybe @wenzeslaus has an idea?

Add --without-pdal to the configure. That should build it without PDAL like before and then you can experiment with compilation once the binder is build.

@chaedri Would you mind to give this another try on binder?

I'm still getting an error when I try it in Binder:

checking whether to use PDAL... yes
Package geos was not found in the pkg-config search path.
Perhaps you should add the directory containing `geos.pc'
to the PKG_CONFIG_PATH environment variable
Package 'geos', required by 'pdal', not found

Also, you can test it anytime from this url:

Looks like the PDAL version for 18.04 is too old, so I removed it. However, looks like Binder is upgrading to 22.04 soon, so we will need to revisit this.
