Build expects static library libColPack.a to be compiled with -fPIC

[yurivict]

/usr/local/bin/ld: /usr/local/lib/libColPack.a(CoutLock.cpp.o): relocation R_X86_64_32 against symbol `_ZN7ColPack8CoutLock8coutLockE' can not be used when making a shared object; recompile with -fPIC

Generally static libraries are built with non-position-independent code.

cmake should link it with a shared library if position-independent code is expected.
