Downloading and Including cmakepp in a CMakeLists.txt

This sample shows you how to include cmakepp in your CMakeLists.txt. If you do not have cmakepp the script automatically downloads it from github.

Prerequisites

• CMake version >=2.8.12
• bash, powershell or cmd.exe
• cmakepp.cmake

Usage

# create a build dir
sample folder/> mkdir build 
sample folder/> cd build 
# generate the project
sample folder/build/> cmake -DCMAKE_RUNTIME_OUTPUT_DIRECTORY=bin-DCMAKE_RUNTIME_OUTPUT_DIRECTORY_DEBUG=bin .. 
-- Building for: Visual Studio 12 2013
-- The C compiler identification is ;MSVC 18.0.31010.0
-- The CXX compiler identification is ;MSVC 18.0.31010.0
-- Check for working C compiler using: Visual Studio 12 2013

# build the configured project
sample_folder/build/> cmake --build . 
... build output ...
# run executable
sample folder/build/> bin/myexe 
hello

CMakeLists.txt:

cmake_minimum_required(VERSION 2.8.12)

## be sure to have the compiled cmakepp in the project dir
if(NOT EXISTS "${CMAKE_SOURCE_DIR}/cmakepp.cmake")
    file(DOWNLOAD "https://github.com/toeb/cmakepp/releases/download/v0.0.3/cmakepp.cmake" "${CMAKE_SOURCE_DIR}/cmakepp.cmake")
endif()
include("cmakepp.cmake")

## now that cmakepp is available it is ready to use.
## and you can use it in you normal CMakeLists.txt
project(sample03)

# write a simple main file
fwrite("main.cpp" "
#include <iostream>
int main(){
  std::cout << \"hello\" << std::endl;
}")

# and create an executable form it
add_executable(myexe main.cpp)
