[CMake] using cmake to install dlls into windows/system32

Thu Dec 17 17:44:07 EST 2009

This seems to work, although I don't think it's the ideal solution:

CMakeLists.txt
    install (FILES drivers/driver.dll
             DESTINATION sysdir/)

    set (CPACK_NSIS_EXTRA_INSTALL_COMMANDS "
        CopyFiles \\\"$INSTDIR\\\\sysdir\\\\driver.dll\\\" \\\"$SYSDIR\\\"
    ")

This gets the dll into the windows system directory, but there are still some issues I'm sorting through:
Versioning of the dll: what if the file was already there and there is already a newer version?
                How to uninstall only if nothing else is using the dll.

It appears that nsis has some helper functions: UpgradeDLL, AddSharedDLL, but I'm not sure yet how to include/call them through CMakeLists.txt.  Does anyone have any insight?  Thanks!

They're device driver dlls for use system-wide.

What's the reason they need to be there?

You should avoid this if at all possible.
Install dlls next to your program, not in the system32 directory.

Do you have a reason you need to install a dll there?

Does anyone have an example of how to install dlls into %WINDIR%/system32 using cmake/ cpack/nsis?  Thanks!
