I want to include caffe in my project. This is the folder structure of the project:

The error is:

CMake Error at CMakeLists.txt:55 (FIND_PACKAGE):
By not providing "FindCaffe.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Caffe", but
CMake did not find one.

Could not find a package configuration file provided by "Caffe" with any of
the following names:

CaffeConfig.cmake
caffe-config.cmake

Add the installation prefix of "Caffe" to CMAKE_PREFIX_PATH or set
"Caffe_DIR" to a directory containing one of the above files. If "Caffe"
provides a separate development package or SDK, be sure it has been
installed.


-- Configuring incomplete, errors occurred!


I have
set
up Caffe_DIR and other required variables. But it still gives the same errors. I removed the previous [cmake] cache so thats not the problem. I cant figure out how to resolve this problem and I need to use Caffe in the project. Please help.

Answer

You want to set your CMAKE_MODULE_PATH to location where cmake module files are located for Caffe project, which would be directory pointed to below:

.
├── AUTHORS
├── ChangeLog
├── cmake          <---------Set Caffe_DIR it to this directory
│   ├── FindCaffe.cmake
│   └── FindCUDA.cmake

If that doesn't work then you should set your Caffe_DIR to the above directory and make sure your rename the files under that directory to one of the names mentioned in the following error:

  Could not find a package configuration file provided by "Caffe" with any of
  the following names:

    CaffeConfig.cmake
    caffe-config.cmake
