[CMake] Detecting changed libraries

[Nico Galoppo]

Hi,

I have a project set up where I genererate optimized/debug libraries
depending on the build type. In the debug build, a 'd' postfix is
added with CMAKE_DEBUG_POSTFIX. However, when building the unit tests
from the same project tree, the updated link library is not detected
and hence the unit tests are not rebuilt. If I delete the unit test
binaries to force a rebuild, the correct (debug) link library is
linked in. What am I missing here? CMakeLists.txt attached.

Thanks.
