Hi,
It seems you don't have oracle instantclient (oci) installed in a
place where QGIS could find it.
If you take a look in CMakeCache.txt (in your build folder where there
is qgis.sln), you need to have this two lines correctly set
//Path to a file.
OCI_INCLUDE_DIR:PATH=C:/OSGeo4W64/include

I was able to build it in Visual Studio 2017 doing some changes at the

However, I can't get any oracle support. The button is not present at the
layer browser window and in DB Manager I get this error when try to connect
to any oracle database:
