[CMake] Link to exe but not shared

[John Biddiscombe]

I have a problem with MPI on a new cluster...

To link all *.so shared libraries I need to set my MPI extra libraries to
MPI_EXTRA_LIBRARY                
/opt/hpmpi/lib/linux_amd64/libmpio.so;/opt/hpmpi/lib/linux_amd64/libmpi.so;
but when linking executables, I need to add
/opt/hpmpi/lib/linux_amd64/libmpiCC.a

the problem being that there is no dynamic build of libmpiCC and if I 
include this in the link line for the shared libs, I get a ton of errors 
about fPIC incimpatibility etc.

As it turns out, the lib is only required at the final link to an 
Executable.
Option 1) Add another MPI_EXE_LIBRARY to cmake and then modify all the 
cmakelists files in paraview etc to use the usual MPI_LIBRARIES on 
shared, and MPI_LIBRARIES+MPI_EXE_LIBRARY on exes

Option 2). Is there some way of specifying a library, but only for 
inclusion with exes but not shared libs (or vice versa).

thanks

JB
