Getting this error now "fatal error LNK1112"

[larslight11]

So i built the files already for the nextcloud client with

cmake -G "Visual Studio 15 2017 Win64" .. -DCMAKE_INSTALL_PREFIX=C:\Nextcloud\desktop\build -DQTKEYCHAIN_INCLUDE_DIR=C:\qtkeychain-0.9.0\build\Debug  -DZLIB_INCLUDE_DIR=C:\zlib\include -DZLIB_LIBRARY=C:\zlib\lib\zlib.lib -DQT_PATH=C:\Qt\5.12.6\msvc2017_64\bin -DCMAKE_BUILD_TYPE=Debug -DNO_SHIBBOLETH=1

After that when i try to build it with

cmake --build . --config Debug --target nextcloud

Before it was giving me this error

  module machine type 'x86' conflicts with target machine type 'x64'

So then i realised that i built my QTKEYCHAIN with msvc2017 not msvc2017_64 , because i tried to build it with the 64bit (msvc2017_64) but it gave me this error

"C:\qtkeychain-0.8.0\build\ALL_BUILD.vcxproj" (default target) (1) ->
"C:\qtkeychain-0.8.0\build\qt5keychain.vcxproj" (default target) (3) ->

Someone please guide on how to resolve this step by step ,it would be much appreciated as its my first C++ project and its taking so long just to build it.

Compiler and after that the linker are searching for openssl headerfiles and library with correct bitness. So perhaps you haven't openssl -sources and library in your search path.
The same holds for QT-import libraray Qt5Cored.lib so that after build process the application can use Qt5Cored.dll.
