Test Plan

Builds fine on:

• 11.3 aarch64
• 11.3 amd64
• 11.3 armv6
• 11.3 i386
• 12.0 amd64
• 12.0 i386
• 12.1 aarch64
• 12.1 amd64
• 12.1 armv6
• 12.1 armv7
• 12.1 i386
• 13.0 amd64
• 13.0 i386
• Base GCC 4.2.1 (mimics powerpc*, mips*, riscv64)
• x11/libinput (the only consumer)

Works fine on:

• Bamboo Pen&Touch (CTH-470)
• x11-drivers/xf86-input-libinput
• x11-wm/sway

• Fix upstream URL

[jbeich]

• Sort USES per ports-mgmt/portfmt

[jbeich]

• Drop USES=pkgconfig as it's unused like USES=tar:bzip2

[jbeich]

• Revert last change (add back USES=pkgconfig) due to botched testing

[jbeich]

• Switch Meson fix to the version merged upstream

Not tested but looks good.
Commit messge should also say that we install those new layouts files (and why).

"Why" is an existing bug in autotools-based build i.e., post-patch missed data/layouts/Makefile.am.

• Rebase

Thanks for the explanation.

Have you checked that downstream consumers are ok with the static library disappearing?
Once that's done, this is OK.

"x11/libinput (the only consumer)" has been in Test Plan before you've asked.

Once that's done, this is OK.

I've also tested whether libinput works properly without rebuild.
