libCLHEP not copied on 'make install'

[DavidWalz]

Using the default CLHEP from get_externals.sh the library files are not copied to the install directory.
libCLHEP-2.0.4.3.a
libCLHEP-2.0.4.3.so

[PeterSchiffer]

I usually set
export LD_LIBRARY_PATH=/my/CRPropa/installation/External/2.0.4.3/CLHEP:$LD_LIBRARY_PATH

But it is probably more user friendly if it would be copied like the other external libraries

[DavidWalz]

That sounds like you don't 'make install' and instead set the path variables to your source dir.
The thing is that CRPropa2 supports 'make install' with the exception of said library, so it should be just a small fix.
