Build with shared libs off - fails with coretranTest

[rmcd-mscb]

Building cortran with shared libs off fails with coretranTest. Build succeds with coretran but fails with the test as below. Build with sharedlibs on succeeds. Not sure if this is a cmake issue or not. Any help would be appreciated.
