[CMake] Sourcefiles compile but no library built

[David Cole]

Is it just a case-sensitive typo?

You say make complains that it can't find "libUtil.so" -- but your
actual library should be named "libutil.so" (lower case u) according
to your add_library call. (I'm assuming MIIND_LIBRARY_PREFIX is the
empty string...?)

If that's not it, you can use "make VERBOSE=1" to gather more details
about what is being built. You should see some sort of linking step
for your "util" target during a clean (start from scratch in an empty
build tree) make.


HTH,
David
