I try to build my app with CMake on Mac OS X, I get the following error:
Linking CXX shared library libsml.so
ld: unknown option: -soname
collect2: ld returned 1 exit status
make[2]: *** [libsml.so] Error 1
make[1]: *** [CMakeFiles/sml.dir/all] Error 2
make: *** [all] Error 2
This is strange, as Mac has .dylib extension instead of .so.
There's my CMakeLists.txt:

There was no error on Linux.
Build process:
cmake -D BuildType=Debug -D LibraryType=shared .
make
I found, that incorrect command generate in CMakeFiles/sml.dir/link.txt. But why, as the goal of CMake is cross-platforming..
How to fix it?
