[Kde-bindings] Issues Building Qyoto (assemblygen) on Mac OSX Lion & 64-bit mono

Vivek,

The key here was this - http://www.mono-project.com/Interop_with_Native_Libraries#lib-name-note. As you saw, Qyoto used to append a "2" after "so" - ".so.2". As you can read at the link, this caused the need of the DLL map (now removed) which in turn prevented the *.dylibs from being found because they were not mentioned in it. So I needed to get rid of this ".2" at the end. That's why I simply removed these properties:

VERSION 2.0.0
SOVERSIOH 2

from the CMake lists so that I get just <libname>.so. As in all lists except one these were the only properties specified, I deleted the whole set_target_properties statements.

Nice to hear you are doing some tests. Good luck and be sure to write here about any problems you may find.

Hey Dimitar, 

Thanks, make & make install now work!  

Just curious, how'd you reason that you just needed to remove the target properties field? I'm still a bit of a newbie to cmake. 

Going to try some code tests (maybe attempt compiling synapse.im) soon.

Also, do the same for each assemblygen/assemblies/qyoto-<QtModule>/CMakeLists.txt (there is an <dllmap dll=\"qyoto-qtcore-native\" target=\"libqyoto-qtcore-native.so.2\"/>, just change ".so.2" to ".dylib").
