Comment 1 for bug 1668940

Hello and thank you for this report! It does seem like what is missing is a build-dependency on libcephfs-dev (also needed on Debian):

Checking for header cephfs/libcephfs.h : 03:18:32 runner /usr/bin/gcc -g -O2 -fdebug-prefix-map=/<<BUILDDIR>>/samba-4.5.4+dfsg=. -fPIE -fstack-protector-strong -Wformat -Werror=format-security -D_FILE_OFFSET_BITS=64 -MD -D_FILE_OFFSET_BITS=64 -Wdate-time -D_FORTIFY_SOURCE=2 -I/usr/local/include -D_SAMBA_BUILD_=4 -DHAVE_CONFIG_H=1 -D_GNU_SOURCE=1 -D_XOPEN_SOURCE_EXTENDED=1 ../test.c -c -o default/test_1.o
no

Based upon the build-log for the 17.04 version. I expect the same output/missing file on prior versions. I am building a test version for 17.04 with the fixed b-d first and then will submit the bug to Debian and upload for 17.04.

Thanks,
Nish
