Normally "make install" would install all files in some predifined
paths on your system, given that you did not specify an individual
target.

In my case, make install puts the mentioned file to
/usr/local/lib/gnome-commander/libgcmd.so.0

When running "make install" as root you see in the very first lines where the 
file is installed at:

# make install
Making install in libgcmd
make[1]: Verzeichnis „/home/uwe/Programmieren/Projekte/gnome-commander/libgcmd“ 
wird betreten
make[2]: Verzeichnis „/home/uwe/Programmieren/Projekte/gnome-commander/libgcmd“ 
wird betreten
 /bin/mkdir -p '/usr/local/lib/gnome-commander'
 /bin/sh ../libtool   --mode=install /usr/bin/install -c   libgcmd.la 
'/usr/local/lib/gnome-commander'
libtool: install: /usr/bin/install -c .libs/libgcmd.so.0.0.0 
/usr/local/lib/gnome-commander/libgcmd.so.0.0.0
                                      
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
libtool: install: (cd /usr/local/lib/gnome-commander && { ln -s -f 
libgcmd.so.0.0.0 libgcmd.so.0 || { rm -f libgcmd.so.0 && ln -s libgcmd.so.0.0.0 
libgcmd.so.0; }; })

In the last line the link from libgcmd.so.0 to libgcmd.so.0.0.0 is created.

With the tool "strace" you can check where Gnome Commander tries to find the 
file:

strace -o /tmp/gcmd.log gnome-commander; grep libgcmd.so.0 /tmp/gcmd.log

openat(AT_FDCWD, 
"/usr/local/lib/gnome-commander/glibc-hwcaps/x86-64-v2/libgcmd.so.0", 
O_RDONLY|O_CLOEXEC) = -1 ENOENT (Datei oder Verzeichnis nicht gefunden)
openat(AT_FDCWD, 
"/usr/local/lib/gnome-commander/tls/x86_64/x86_64/libgcmd.so.0", 
O_RDONLY|O_CLOEXEC) = -1 ENOENT (Datei oder Verzeichnis nicht gefunden)
openat(AT_FDCWD, "/usr/local/lib/gnome-commander/tls/x86_64/libgcmd.so.0", 
O_RDONLY|O_CLOEXEC) = -1 ENOENT (Datei oder Verzeichnis nicht gefunden)
openat(AT_FDCWD, "/usr/local/lib/gnome-commander/tls/libgcmd.so.0", 
O_RDONLY|O_CLOEXEC) = -1 ENOENT (Datei oder Verzeichnis nicht gefunden)
openat(AT_FDCWD, "/usr/local/lib/gnome-commander/x86_64/x86_64/libgcmd.so.0", 
O_RDONLY|O_CLOEXEC) = -1 ENOENT (Datei oder Verzeichnis nicht gefunden)
openat(AT_FDCWD, "/usr/local/lib/gnome-commander/x86_64/libgcmd.so.0", 
O_RDONLY|O_CLOEXEC) = -1 ENOENT (Datei oder Verzeichnis nicht gefunden)
openat(AT_FDCWD, "/usr/local/lib/gnome-commander/libgcmd.so.0", 
O_RDONLY|O_CLOEXEC) = 3

In the last line the file was foundHope that helps in your investigation
