[Answered with link] Documentation for QMAKE_CFLAGS_RELEASE options ?
Just a question, on wiki I read that you can add "-MP2" to QMAKE_CFLAGS_RELEASE variable in %QTDIR%\mkspecs[some value]\qmake.conf.
Where can I find documentation about available options? "-MP2" means static linking.
Everything you put in that variable will be passed to your compiler during compilation for release targets. So, for documentation, you need to look at the documentation of your compiler (and sadly, every compiler has it's own set of flags).
OK, for MSVC compiler this page has info: http://msdn.microsoft.com/en-us/library/19z1t1wy(v=vs.100).aspx
so here it's about multithreading, not static linking...
