This should be working nowadays without any issues. We have fixed all the windows and qmake file related issues in the QtSerialPort build system.
Please try again with a later version.
Question
I have downloaded qtserialport files from git and tried to compile it in qt-creator. At first I tried "Build" option, but have tried "Run qmake" as well.
Both give me same result
:-1: error: Failed to run: C:\Qt\Qt5.0.1\5.0.1\msvc2010\bin\syncqt.bat -module QtSerialPort -mkspecsdir C:\Qt\Qt5.0.1\5.0.1\msvc2010/mkspecs -outdir C:/qtserialport-build-Desktop_Qt_5_0_1_MSVC2010_32bit-Debug C:/qt-qtserialport
