You mean the "if(WIN32)" clause and the addition of "reverse.h" in SET
(REV_SRC reverse.cpp reverse.h)? Otherwise I think visual studio projects
wont add the header file to the solution's source file hierarchy.

I tried in the way you have mentioned, but the error persists (fatal error
LNK1104: cannot open file 'reverse.lib') . I have also removed the entry
for adding subdirectory (the lib/reverse) in my src folder's cmake file (
ADD_SUBDIRECTORY(lib/reverse)). The following is my main cmake file
#Root cmake file
cmake_minimum_required (VERSION 2.6)
PROJECT (Tutorial)
ADD_SUBDIRECTORY(src/lib/reverse)
ADD_SUBDIRECTORY(src)
SET (DO_TEST false CACHE BOOL "Enable Testing?")
if(DO_TEST)
ENABLE_TESTING()
ADD_SUBDIRECTORY(tests)
endif(DO_TEST)
Thank you very much,
