[Csnd-dev] CMakeLists.txt for cs7

Does anyone claim control of this fie? I have a variation that
seems to get GETTEXT right at least for my inux, and also hae a variation
for pthread support that fails with the message

/usr/lib64/gcc/x86_64-suse-linux/7/../../../../x86_64-suse-linux/bin/ld: CMakeFiles/csound-bin.dir/csound/sched.c.o: undefined reference to symbol 'pthread_detach@@GLIBC_2.2.5'
/usr/lib64/gcc/x86_64-suse-linux/7/../../../../x86_64-suse-linux/bin/ld: /lib64/libpthread.so.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

and I cannot see what is wrong.  There are also aspects of
CMakeLists.txt that feel wrong but I am uncertain as to what is the
intent.

It would be nice to have his stable and sane.
