Link Errors on First Build (LNK2001) in Qt Vs Tools projects with RC resources

When attempting to build certain projects with Windows resources (.RC file) with Qt VS Tools enabled, the first build (right-click and choose "Rebuild", or "Clean" and then "Build") results in link errors. The second build succeeds. When the project is converted back to regular type (by removing   <Keyword>QtVS_v301</Keyword> from .vcxproj file) - the issue goes away.

I stripped out everything except the bare minimum in our solution to replicate the issue.

To replicate:

1) Extract the attached Test.zip

2) Open System.sln

3) Right-click "SAS" project and choose "Rebuild", the following error occurs:

1>SAS.vcxproj -> c:\Temp\dummy\SAS\..\programsDebug\SAS.dll
1>SAS.vcxproj -> ..\programsDebug\SAS.pdb (Full PDB)
1>SAS.def : error LNK2001: unresolved external symbol StartProcess

4) Try to rebuild again - same error result

5) Right click "SAS" and choose "Build", the builds succeeds:

1>SAS.vcxproj -> c:\Temp\dummy\SAS\..\programsDebug\SAS.dll
1>SAS.vcxproj -> ..\programsDebug\SAS.pdb (Full PDB)
========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========

6) Manually edit SAS.vcxproj and remove " <Keyword>QtVS_v301</Keyword>" line

7) Right-click "SAS" project and choose "Rebuild", the build succeeds

8) Restore the project to Qt by putting the keyword back

9) Rebuild - resulting in error

10) Remove the RC file. Rebuild - resulting in success.
