[Insight-users] Trying to build dynamic libraries - no success

[Gamal Akabani]

Dear ITK users - I am new to ITK. I was able to build the static 
libraries; however, when I set to dynamic libraries I got the following 
error.

Building shared library

I am not sure what is wrong as I only changed

> BUILD_SHARED_LIBS:BOOL=ON
The rest remained the same as before and it compile successfully. Any 
ideas what is wrong?
TIA.
