Compile Caffe's project using cmake

Use CMake compile Caffe Project

Recently I was compiling a Caffe Project , This dependency is always missing at compile time , That dependency , Here are a few lessons learned .

1. Caffe You have to use CMake To compile

I started with what the author provided Makefile To compile Caffe, As a result, when compiling my project , There will always be no Caffe Dependence , So I've been reporting mistakes .

2. Boost The library cannot be used apt Tool to install

apt-get The installation of tools is simple , Save a lot of trouble , The same is true of me , compile Caffe Time is no problem , But compile later Caffe Project time , There will be many strange problems , Later, I used the source code to install Boost success , The time spent in the middle is simply touching .

3. CMake Precompiled output

I use CLion To compile , Here, I will directly attach build The output of the console , You can see my dependent version below .

4. CMakeLists.txt

Here also directly to my CMakeLists.txt Of ,CMakeList.txt Of find_package It's always windy , Not intelligent at all ( Make complaints about , But it may also be that my younger brother is incompetent ). The following is the correct way of writing which I have tried for many days and nights .

cmake_minimum_required(VERSION 3.21)

endif()

if(CPU_ONLY)
    add_definitions(-DCPU_ONLY)
endif()
