[CMake] Add sources to a target library after add_library()?

[Loaden]

Yes, it simply for GCC. But it is diffrent for MSVC compiler.
for MSVC, we have to use a .cpp file, e.g. stdafx.cpp to support
precompiled. (/Yc flags)
For now, I have to implement it like this to support both MSVC and GCC's
PCH support.

> add_dependencies(${target} Botan)

>     use_precompiled_header(${target} "${sources}")
