Hi

when I build ‘dlp_structured_light_sdk’ on Qt Creater 3.5.1(opensource) based on Qt 5.5.1(MSVC 2013, 32bit) , it got some errors, as follows: 

C:\TexasInstruments-DLP\TIDA-00254_3D_Scanner_LCr4500_PGFlea3-1.1\dlp_structured_light_sdk\src\common\image\image.cpp:397: error: undefined reference to `cv::imread(cv::String const&, int)'

collect2.exe:-1: error: error: ld returned 1 exit status

I installed cmake-3.4.3-win32-x86.exe and opencv-3.1.0.exe on my win7 PC following TIDA-00254: Accurate Point Cloud Generation for 3D Machine Vision Applications using DLP®Technology and Industrial Camera User's Guide.

How can I solve these problems? Help me, please! Thanks.

Best regards.
