I got this problem when trying to compile opencv using Cmake and mingw.
for Cmake:
sourcecode is located in "C:\CPP Libraries\OpenCV-2.4.13\opencv\sources"
where the binaries are goint to be build is in: "C:/CPP Libraries/OpenCV-2.4.13/opencv/build/x64/mingw"
I've already used Cmake to generate the makefile.
when i run the makefile:
C:\CPP Libraries\OpenCV-2.4.13\opencv\build\x64\mingw>mingw32-make
this is the output that I get after 31%
[ 31%] Building CXX object modules/highgui/CMakeFiles/opencv_highgui.dir/src/window_w32.cpp.obj

Does anyone knows a solution, because i have no clue about this one.
