[CMake] Question regarding project structure

I have a problem with add_executable(). Our Kernel library includes main.cpp, so all our existing linker command does is to take libKernel.a and make it an executable:

g++ -o _gnuRelease/MyExe -ldl -Wl,-whole-archive,-export-dynamic ../Kernel/_gnuRelease/libKernel.a

So I have no source files to specify. Does 'exe.cxx' (above) have special properties or is it just a placeholder? If the latter, how can I build an executable with no source files specified?
