Make the pkgconfig file of Guile relocatable.

Make the pkgconfig file of Guile relocatable.

Currently, the guile-3.0.pc.in in 'meta' use the variable substitution
directly.

prefix=@prefix@
exec_prefix=@exec_prefix@
bindir=@bindir@
libdir=@libdir@
includedir=@includedir@
datarootdir=@datarootdir@
datadir=@datadir@
pkgdatadir=@datadir@/guile
pkgincludedir=@includedir@/guile

sitedir=@sitedir@
extensiondir=@libdir@/guile/@GUILE_EFFECTIVE_VERSION@/extensions
siteccachedir=@libdir@/guile/@GUILE_EFFECTIVE_VERSION@/site-ccache
libguileinterface=@LIBGUILE_INTERFACE@

sitedir, siteccachedir and extensiondir will be subsituted to the full
path of the install path of Guile.

But sometimes I want to install guile module in different
prefix(e.g. NixOS, Guix, flatpak). I have to adjust these variable
manually.

My idea is change the definition of sitedir, siteccachedir, extensiondir
use the variable substition of pkg-config instead of autotools.

For example

sitedir=${datadir}/guile/site/@GUILE_EFFECTIVE_VERSION@
siteccachedir=${libdir}/guile/@GUILE_EFFECTIVE_VERSION@/extensions

....

So I can use

pkg-config guile-3.0 --define-variable=libdir=$MY_PREFIX --variable=siteccachedir

to get the correct install directory.

Thoughts?

hi Zihao!

I think the substitution is OK.
But if you want to package for Guix, you need to go Guix way.
Guix package has made a similar approach, for example, you may check "guix
edit artanis" to see how it substitutes the dir for Artanis.

Best regards.

Sounds reasonable to me.  Would you like to submit a patch?

Thanks,
Ludo’.
