Fix a few CMake build bugs
 2016-10-17 18:45:20 +01:00
Dan Liew 289e51f455 [CMake] Fix building the Java bindings. 
This was broken due to 495ef0f055
and a914822346 adding and removing
source files without updating the CMake build.
 2016-10-17 18:30:49 +01:00
Dan Liew 462d3e8e8b [CMake] Unbreak building the .NET bindings. 
7fefe40f21 broke building the .NET
bindings by renaming the signing key without updating the CMake build.
 2016-10-17 18:19:31 +01:00
Dan Liew 03071db3ed [CMake] Fix building the examples when libz3 is built as a static library. 2016-10-17 18:19:31 +01:00
Dan Liew 4ef55505e7 [CMake] Fix #763 reported by @jirislaby. 
`INTERFACE` was the not appropriate usage requirement to use. However
it only caused a problem when USE_LIB_GMP was enabled. With `INTERFACE`
`-lgmp` was not specified on the link line so `libz3.so` did not have a
reference to the library and linking against `libz3.so` by clients
would fail with missing references to symbols in `libgmp`.
