Please find below a log of building a VS2017 project named PGembeddedSQL
using the joined ECPG extension.

Building the PGEmbeddedSQL.vcxproj with msbuild calls automatically the
ecpg precompiler to precompile the PGEmbeddedSQL.pgc source and produces
PGembeddedSQL.cxx, which in turn is compiled and linked to produce de
PGembeddedSQL.exe

Without the extension, you would have to precompile the
PGembeddedSQL.pcg by hand
