Windows finds DLLs using PATH or the directory of the process'
executable. By outputing those dependend DLLs together with
owncloud.exe, the developer only need to have OpenSSL's bin
and the qtkeychain build directory in his PATH to let the
dynamic linker find them.
As the documentation of RUNTIME_OUTPUT_DIRECTORY points out,
this only affects windows as other platforms don't consider
libraries as runtime targets.
- qtkeychain isn't necessarily in a qt5keychain subdirectory.
- Explicitly add OpenSSL to the include directories
- Make sure that the USE_OUR_OWN_SQLITE3 code is initialized
for csync by calling find_package.
