Failing to compile sqlite_fdw

Hi,
I'm trying to install the sqlite_fdw extension (from here -
https://github.com/pgspider/sqlite_fdw) on postgresql v 9.6.9.

When I tried to compile it with make I got the next error :

sqlite_fdw-master]# make
Makefile:46: ../../src/Makefile.global: No such file or directory
Makefile:47: /contrib/contrib-global.mk: No such file or directory
make: *** No rule to make target `/contrib/contrib-global.mk'. Stop.

then I searched the error and I found the next solution :

sqlite_fdw-master]#make USE_PGXS=1
gcc -Wall -Wmissing-prototypes -Wpointer-arith
-Wdeclaration-after-statement -Wendif-labels -Wmissing-format-attribute
-Wformat-security -fno-strict-aliasing -fwrapv -O2 -g -pipe -Wall
-Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector
--param=ssp-buffer-size=4 -m64 -mtune=generic -fPIC -I. -I./
-I/usr/pgsql-9.6/include/server -I/usr/pgsql-9.6/include/internal
-D_GNU_SOURCE -I/usr/include/libxml2 -I/usr/include -c -o connection.o

It seems that the compilation of the files failed. Do I need to use some
different gcc ? my gcc version :
gcc version 4.4.7 20120313 (Red Hat 4.4.7-23) (GCC)

Any idea ?

Thanks.
