[CMake] Platform tests counts as errors.

[David Cole]

Oh, one more thing... in order to activate that suppress output in VS
chunk of code, you have to turn on the logging feature of
ExternalProject.

include(ExternalProject)
ExternalProject_Add(CxNativeTg
 SOURCE_DIR "${FOO_SOURCE_DIR}"
 CMAKE_ARGS
   -DCMAKE_BUILD_TYPE=Release
  LOG_CONFIGURE 1
)
