Indeed!
I'm not sure why everyone was only adding a lib/pkgconfig/ but
share/pkgconfig/ is also to be added in any custom prefix in
PKG_CONFIG_PATH!
Why it worked inside /usr is because this is already in the defaults
path of pkg-config for the /usr/ or /usr/local/ prefixes but you have
to take care of it for any custom prefix.

Also why can it be in share/ or in lib/? The logic is quite simple: if
this is a library, the pc file goes in lib/pkgconfig/, if this is a
data package, it goes in share/pkgconfig/.
Have fun!
