I could be completly wrong, but you want link a static library to a
program. You don't need CMAKE_EXE_LINKER_FLAGS.
PROJECT(T)
FIND_LIBRARY(_pathAndNameOfLibrary NAMES foo)
ADD_EXECUTABLE(targetname yourSourcefiles)
TARGET_LINK_LIBRARIES(targetname ${_pathAndNameOfLibrary})

In this case the program is linked to foo.so.

You have to make sure that FIND_LIBRARY finds the library (paths, names)
See www.cmake.org/cmake/help/cmake2.6docs.html#command:find_library for
a detailed description
You might come in trouble if both versions (.so .a) exist. If they are
located in different directories, this might help:

Is this really necessary? Live is already difficult enough.
