[CMake] Compiling dll under MSVC 2008

[Tyler Roscoe]

Guess I'll top-post too...

Mike, that article is helpful and OP should definitely read it.

Benoit, I think the specific problem you are having is that you are
setting RUNTIME_ and LIBRARY_OUTPUT_DIRECTORY but not
ARCHIVE_OUTPUT_DIRECTORY. From the docs:

"For DLL platforms the DLL part of a shared library is treated as a
runtime target and the corresponding import library is treated as an
archive target."

I bet you'll find cv7core.lib in your CMAKE_BINARY_DIRECTORY.

hth,
tyler
