How to tell CMake the location and name of gtk4

[vansnyder]

I use Debian 10 Buster. I got gtk4 from the Debian repository. Therein, its name is gtk+4.

When I tried to make gtk-fortran using the instructions in INSTALL.md, CMake said it couldn't find gtk4.

How do I tell CMake where it is and what its name is?

GTK 4 seems to be available only in Debian Bookworm (GTK 4.6.1):
https://packages.debian.org/bookworm/libgtk-4-dev
and in the experimental repository, it seems there is only an old version 3.91.2.

Can you give me more information on the GTK 4 library in your system?

I followed the instructions at https://packages.debian.org/bookworm/amd64/libgtk-4-dev/download. I added deb http://ftp.us.debian.org/debian bookworm main to /etc/apt/sources.list. apt-get install libgtk-4-dev_4.6.1+ds-1_amd64.deb apt-get install libgtk-4-dev apt-get install libgtk-4 were all unable to find the package.

CMake is using pkgconfig to find GTK 4. You may try to use the PKG_CONFIG_PATH variable, like in this example where PLplot was built from sources in FreeBSD:

$ PKG_CONFIG_PATH=/home/osboxes/myPLplot/lib/pkgconfig cmake -D CMAKE_BUILD_TYPE=debug ..

For those of us who don't routinely use CMake, or who have never used it, more explanation in INSTALL.md of how to set it up for gtk-fortran would be useful.

I will improve it tomorrow.
