Outdated paths in INSTALL.in
Concerns an excerpt of 'Readme' file: " .pc files for the various libraries are installed in $exec_prefix/lib/pkgconfig ". In fact, installing Glib on Kubuntu 20.04 have set *.pc files to /usr/local/lib64/pkgconfig . Therefore, running 'pkg-config --cflags glib-2.0' doesn't find its version.
