Creating per-library EXPORT symbols

Makes the changes as discussed here:

I should note that this still doesn't work though (it does create cnip.exe though!) due to link failures in test-suite.exe:

Yeah, I have no idea why the test implementations go into psychecfe.{so,dll} -- it probably makes sense this "doesn't work", because things like TestBinder aren't dllexport'd.

If you're happy, I can just if out (in the top-level CMakeLists.txt) building the tests on Windows:

-set(PSYCHE_TESTS test-suite)
-add_executable(${PSYCHE_TESTS} ${PSYCHE_TESTS_SOURCES})
-target_link_libraries(${PSYCHE_TESTS} psychecfe psychecommon dl)
+IF (NOT WIN32 AND NOT MINGW)
+    set(PSYCHE_TESTS test-suite)
+    add_executable(${PSYCHE_TESTS} ${PSYCHE_TESTS_SOURCES})
+    target_link_libraries(${PSYCHE_TESTS} psychecfe psychecommon dl)
+endif()

This then successfully builds for me.
