[ncl-install] Builded NCL have too more dependent dynamic library at openSUSE Tumbleweed

[王忍之]

Dear NCL Developer：


 I have build ncl 6.4.0 at openSUSE Tumbleweed. gcc version is 7.3.1 . Most of library have been compiled statically.
 such as netcdf 4.5.0, hdf5-1.8.20, hdf, hdf-eos, gdal ..and etc.


 But I fonud ncl binary file is too big (106MB), so I use 'strip' command reduced ncl size. Finally it only have 28MB.


 And I run 'ldd ncl' command . it's output:

 I compared with precompiled binaries. it need too more shared library .So Can you help me how to reduce 'ncl' dependent dynamic library？
