[GNC] Building Gnucash on Fedora 37 - "No package 'glib-2.0' found" error

[Vivek Gani]

Hi,

I'm trying to build gnucash from source (rather than the rpm package or
flatpak for python bindings) on Linux (Fedora 37) and keep running into an
issue where on build I get the error:

```
-- Checking for module 'glib-2.0>=2.56.1'
--   No package 'glib-2.0' found
```

What I've tried so far:
- I've installed glib2.0-devel via `sudo dnf install glib2-devel`
- I've checked via `yum provides */glib2.0.pc` which shows it is in the
`/usr/lib64/pkgconfig` directory.
- I've checked the contents of `echo $PKG_CONFIG_PATH` which shows
directories like `/usr/lib64/pkgconfig` are listed.
- I've tried building gnucash with various different arguments, but similar
to the directions in
https://wiki.gnucash.org/wiki/CMake#GnuCash_Configuration_Variables &
https://wiki.gnucash.org/wiki/Building_On_Linux#Build_using_CMake_and_Ninja
I've tried in my build directory:
`cmake -DCMAKE_INSTALL_PREFIX=$HOME/opt
-DCMAKE_PREFIX_PATH=$PKG_CONFIG_PATH  -DCMAKE_VERBOSE_MAKEFILE=on
../gnucash-4.13`

and get the glib error. It happens also without the CMAKE_PREFIX_PATH, just
running plain `cmake .` in the gnucash source directory, etc.

Any idea what I'm missing to get things to build?

Thanks in advance,
Vivek
