pkgcon/pkg-config cannot find epics-base or epics-base-linux-x86_64

[Jens Georg]

I am not sure if this is an epics-dev problem or a pkgcon/pkg-config issue, but since pkg-config works fine for other packages, I assumed the former.

I have installed epics-dev. It contains the epics-base.pc and the epics-base-linux-x86_64.pc files, yet pkg-config (or pgkcon) cannot find it:

jgeorg @jgeorg-ubuntu2404 /usr/share $ dpkg -l | grep epics
ii epics-dev 7.0.7+dfsg1-5 amd64 EPICS header files

jgeorg @jgeorg-ubuntu2404 /usr/share $ dpkg -L epics-dev | grep pc$
/usr/share/pkg-config/epics-base-linux-x86_64.pc
/usr/share/pkg-config/epics-base.pc

jgeorg @jgeorg-ubuntu2404 /usr/share $ pkg-config --modversion epics-base
Package epics-base was not found in the pkg-config search path.
Perhaps you should add the directory containing `epics-base.pc'
to the PKG_CONFIG_PATH environment variable
Package 'epics-base', required by 'virtual:world', not found
