open62541 library build on Windows differents with release files - cmake

Question

I trying to go into the open62541 project to use it in my solution. My platform is windows.
At first, I downloaded the release files (open62541.h/c) and compiled the server example with GCC compiler (MinGW64).
$ gcc -std=c99 open62541.c myServer.c -l"ws2_32" -o myServer
That works. So my following step was to get the newest master from GitHub, and build it with CMAKE. I used the following CMAKE configuration:
CMAKE configuration
UA_NAMESPACE_ZERO Reduced is used due to FULL will cause CAMKE to fail generate project:
CMake Error at CMakeLists.txt:1156 (message):
File
C:/Users/lukasz/Desktop/open62541-visual/deps/ua-nodeset/Schema/Opc.Ua.NodeSet2.xml
not found. You probably need to initialize the git submodule for
deps/ua-nodeset or set open62541_NODESET_DIR.
That will create a .sln, and simple build all creates open62541.h/c. When I try to compile the example with generated files I got this error:

What causes that difference to released files?
