This sample is showing you how you can use cmake and CMakeLists.txt file to compile your c++ application.
<\/p>\n\n\n\n

Make sure g++<\/strong> installed. If not go to Build and run your first application with g++<\/a> for more help.<\/p>\n\n\n\n

Also make sure make<\/strong> command is installed. If not go to Build and run your first application with make<\/a> for more help.<\/p>\n\n\n\n

If you face command not found: cmake<\/strong> that means it is not there.<\/p>\n\n\n\n

Run following command to see if cmake<\/strong> is installed:\n<\/p>\n

$ cmake --version\nzsh: command not found: cmake\n<\/pre>\n\n\n\n
Installing make<\/h3>\n\n\n\n
  • MacOS 
    $ brew install cmake<\/pre><\/li>
  • Linux
    • Debian\/Ubuntu 
      $ sudo apt install cmake<\/pre><\/li><\/ul><\/li><\/ul>\n\n\n\n
      Building Hello World application<\/h2>\n\n\n\n
      The first step is to create a CMakeLists.txt<\/strong> file to define the build configuration steps for cmake. Add following content:<\/p>\n\n\n\n
      cmake_minimum_required (VERSION 2.6)
      project (Hello)
      set (HELLO_SRCS hello.h hello.cpp main.cpp)
      add_executable(greet ${HELLO_SRCS})<\/pre>\n\n\n\n
      • The first tag cmake_minimum_required<\/strong> is to indicate the minimum version of conan.<\/strong> In this sample I set it to 2.8.12<\/li>
      • The second tag project<\/strong> is to set the project name which I set it to Hello<\/strong>. <\/li>
      • The 3rd tag add_definitions<\/strong> is to set <\/li>
      • Next for compiling your non-executable files as the shared library objects files you can use ADD_LIBRARY<\/strong>. The first parameter is the target and the next parameters are the file names  (.h and .cpp files) you are going to compile them into that non-executable<\/strong> target object file.<\/li>
      • To compile your executable file, you can use ADD_EXECUTABLE<\/strong>. The first parameter is the target and the next parameters are the source code file names (.h and .cpp files) you are going to compile them into that executable<\/strong> target object file.<\/li>
      • At the end, in order to link all of your compiled object files you can use TARGET_LINK_LIBRARIES<\/strong>. The first parameter is the target executable<\/strong> file that you eventually run in command line and the next parameters are the object file<\/strong> names you are going to link them into that executable<\/strong> file.<\/li><\/ul>\n\n\n\n
        Create a folder called build<\/strong> and then use cmake<\/strong> command to build the application. It uses CMakeLists.txt<\/strong> file to compile the sources to object files.<\/p>\n\n\n\n
        Create a folder called build<\/em> and then use conan install<\/em> command to build the application.<\/p>\n\n\n\n
        $ mkdir build
        $ cd build
        $ conan install ..
        <\/pre>\n\n\n\n
        For Linux and Mac<\/p>\n\n\n\n
        $ cmake ..
        $ cmake --build .
        <\/pre>\n\n\n\n
        For Windows:<\/p>\n\n\n\n
        $ cmake .. -G \"Visual Studio  Win64\"
        $ cmake --build . --config Release<\/pre>\n\n\n\n
        Running the app<\/h2>\n\n\n\n
        Run greet<\/strong><\/em> command like this:<\/p>\n\n\n\n
        $ .\/greet
