CMake cross-compiling generate invalid linker options

Question

I am using CMake for compiling in Linux and Windows with a specific toolchain (nios2-linux-gnu-g++.exe (Sourcery CodeBench Lite 2013.05-43) 4.7.3).

The options "-Wl,--out-implib,myapp.dll.a" and "-Wl,--major-image-version,0,--minor-image-version,0" generated from CMake to linker are invalid for compiler.

Compiler errors:

• nios2-linux-gnu/bin/ld.exe: unrecognized option '--out-implib'
• nios2-linux-gnu/bin/ld.exe: unrecognized option '--major-image-version'
• nios2-linux-gnu/bin/ld.exe: unrecognized option '--minor-image-version'

I solved the problem by setting the variable set(CMAKE_SYSTEM_NAME Generic) in the toolchain file. I was using Windows than Generic, when I changed to "Generic" the generation works fine.
