[cmake-developers] Visual Studio 2015 FastLink

[Thomas (QbProg)]

Thanks for the commit!
I digged through the msbuild targets of visual c++ 14 and it seems that for
the moment, generating full PDBs simply switches back the
"GenerateDebugInformation" value to "Debug".
I propose to wait until there is a documented switch or the behavior is
more clear.

This is what I found in Microsoft.CppCommon.targets:

<!-- Generate full PDB. For now call link without /debug:fastlink. -->
<GenerateDebugInformation Condition="'%(Link.GenerateDebugInformation)' ==
'DebugFastLink' and '%(Link.FullProgramDatabaseFile)' ==
'true'">Debug</GenerateDebugInformation>
