dll is not installed on Windows

tlx.dll is not installed on Windows when we build shared lib

here is a patch:

--- a/tlx/CMakeLists.txt
+++ b/tlx/CMakeLists.txt
@@ -86,6 +86,7 @@ if(TLX_BUILD_SHARED_LIBS)
   install(TARGETS tlx
     EXPORT tlx-targets
     COMPONENT Libraries
+    RUNTIME DESTINATION ${TLX_INSTALL_BIN_DIR}
     ARCHIVE DESTINATION ${TLX_INSTALL_LIB_DIR}
     LIBRARY DESTINATION ${TLX_INSTALL_LIB_DIR})

It fixes MinGW, but it's not sufficient for Visual Studio because symbols are not exported (CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS is a (dirty) solution, the best would be to properly export public symbols with __declspec(dllexport)).
