Same thing happens to me also. The problem is of RPATH settings. the path
your cmakelist links to while installing is not set for the sub directories
when you try to build and install it from your main directory "vos".
Therefore you need to do the following:

# use, i.e. don't skip the full RPATH for the build tree
SET(CMAKE_SKIP_BUILD_RPATH  FALSE)

# when building, don't use the install RPATH already
# (but later on when installing)
SET(CMAKE_BUILD_WITH_INSTALL_RPATH FALSE)

# the RPATH to be used when installing
SET(CMAKE_INSTALL_RPATH "/bin")

# add the automatically determined parts of the RPATH
# which point to directories outside the build tree to the install RPATH
SET(CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE)

after doing this once when you do make install it will work and install the
exeutabled in /bin.
No need to set all this variables in the sub directory. it is valid for all
sub dirs.

For further inf. on RAPTH refer this link:
http://www.cmake.org/Wiki/CMake_RPATH_handling

It provide all details pertainign to RPATH settings.

Hope all this will work for you.
