[CMake] Unknown origin of compiler flag on Cray

[Will Dicharry]

Hi All,

I am experiencing a strange problem on Cray XT machines running CNL 
compute nodes with the PGI compiler.

It appears that something is adding the flags "-Bstatic -Bdynamic" (in 
that order) to the link line.  It looks like the Linux.cmake platform 
module sets the the variable CMAKE_${type}_DYNAMIC_C_FLAGS to -Bdynamic. 
   But that's the only reference to the flags that I can find anywhere 
in the project.

The cache does not contain the flags, my list files do not contain the 
flags, and as far as I can tell, none of the modules I am using add the 
flags (the only modules I call are a custom exodus find module, a custom 
netcdf find module, and the HDF5 find module I submitted earlier this 
week).  Also, all of the libraries built by my projects and the 
libraries found by cmake with find_package are static.

The flags are causing problems because we use the Cray provided wrapper 
compilers, which add a few additional libraries to the link line, and 
the ordering of the flags causes the linker to use the dynamic version 
of some libraries, which is unsupported by the CNL compute nodes.

Has anyone seen something like this before, or does anyone have any 
suggestions on where else I should look to find the culprit?

Thanks,
--Will
