ConfigureChecks.cmake:7 does
pkg_get_variable(XKBDIR xkeyboard-config xkb_base)
if (NOT EXISTS "${CMAKE_SYSROOT}/${XKBDIR}")
assuming pkg-config returns an unprefixed path. This build sets
PKG_CONFIG_SYSROOT_DIR, so pkg-config already applies the sysroot and XKBDIR
comes back absolute. Prefixing again produced
.../sysroot//mnt/data/.../sysroot/usr/share/X11/xkb
and configure aborted although the directory is present (verified: the xkb
directory IS in plasma-desktop's sysroot, and xkeyboard-config.pc correctly
records xkb_base=/usr/share/X11/xkb).
Accepts either form instead of un-prefixing XKBDIR: which one pkg-config
returns depends on PKG_CONFIG_SYSROOT_DIR, so testing both is correct in both
configurations and keeps the check meaningful rather than disabling it.
