Compiling opencv samples: unknown cmake command ocv_check_dependencies

Question

I am trying to build the OpenCV samples which come with the source package and I get the following:

CMake Error at CMakeLists.txt:10 (ocv_check_dependencies)         


        

Answer 1

I got it.

In order to build the samples one has to change the default configuration for cmake by providing it via -D. What I did wrong was that I tried to execute cmake from within the samples directory.

The proper way to build the samples is invoking cmake like so (from within the root directory of the unpacked archive):

cmake -DBUILD_SAMPLES .

which will turn samples ON. One can proceed using make, make install than. The samples can be found in bin after building.
