on your homepage you state that wxCam requires CImg-1.2.
I'm afraid this is not correct. Installing wxCam-1.0.7 with CImg-1.3.1 failed because:
"frame.cpp:485:16: error: ‘struct cimg_library::CImg<unsigned char>’ has no member named ‘laplacian’"
It seems this function was added to CImg in CVS-revision 1.320 unfortunately I couldn't find out what CImg-version that
corresponds to. With the latest version (CImg-1.4.6) wxCam compiles fine. So rev 1.320 (and thus laplacian()) seems to
be somewhere between version 1.3.1 and 1.4.6.
