[CMake] cmake_cxx_link_executable issue

[Piotr Bialek]

Dear Users,

I'm trying to cross compile with clang. I set cmake_compiler, 
cmake_linker, etc.
During the linking CXX executable all flags, libs, files, etc. are 
getting  from somehow created file ./Main/CMakeFiles/Build.dir/link.txt.

The problem is, that when I change linker by setting 
CMAKE_CXX_LINK_EXECUTABLE, no files or flags are generated in link.txt 
and I get message like: "x86_64-pc-linux-gnu-ld: no input files".

My question is how to generate those flags and files into the link.txt 
and why they disappeared by changing linker?

Best regards,
Piotr Bialek
