    Description

      When using Visual Studio 16.8.3 or 16.8.4, with Qt addins 2.6.x or 2.7.0.0, I have regularly an error with multiple process which seem to access to the same log file "moc.read.1u.tlog".

      This error is also present in the last build 2.7.0.0 (generate after this bug fix QTVSADDINBUG-827)

      Here an exemple of the error:

      C:\Users\username\AppData\Local\QtMsBuild\qt_globals.targets(368,5): error MSB3491: Could not write lines to file "D:\b63dd3bbf6a8743c\compilation\Debug_x64\RshProject\RshProject.tlog\moc.read.1u.tlog". The process cannot access the file 'D:\b63dd3bbf6a8743c\compilation\Debug_x64\RshProject\RshProject.tlog\moc.read.1u.tlog' because it is being used by another process.
Done building project "RshProject.vcxproj" -- FAILED.

      Not that option "Parallel Process" is set to "Yes" on all Qt task (moc, ui, qrc). It's perhaps the source of this error.
