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
//Path to a library.
OCI_LIBRARY:FILEPATH=C:/OSGeo4W64/lib/oci.lib
I think you need to install the two package oci and oci-devel with
OSGEO4W installer et restart package.cmd (or package-nightly.cmd).
Regards,
Julien
