Your issue has nothing to do with cmake, but with used compilers / runtimes.

Your library will be possibly compatible with gcc 4.1 if it is not linked to libstdc++. To achieve this you have to elemeinate all std:: usages or only carefully chosen subset which does npot require linking. You also should not use any std:: types in public API of your library.
