Conan and CMake files

• A sample from conanfile.txt in the root directory:

[requires]
xtensor/0.20.10@omaralvarez/public-conan
...

[generators]
cmake
...

• The CMakeLists.txt at the root directory:

cmake_minimum_required(VERSION 2.8.12)
project(PackageTest CXX)

if(NOT CMAKE_BUILD_TYPE)
  set(CMAKE_BUILD_TYPE Release)
endif()

include(CheckCXXCompilerFlag)

set(CMAKE_CXX_STANDARD 14)

CHECK_CXX_COMPILER_FLAG("-march=native" COMPILER_SUPPORTS_MARCH_NATIVE)
if(COMPILER_SUPPORTS_MARCH_NATIVE)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -march=native")
endif()

CHECK_CXX_COMPILER_FLAG("-mtune=native" COMPILER_SUPPORTS_MARCH_NATIVE)
if(COMPILER_SUPPORTS_MARCH_NATIVE)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mtune=native")
endif()

find_package(OpenMP REQUIRED) # Find the package

include(${CMAKE_BINARY_DIR}/conanbuildinfo.cmake)
conan_basic_setup()
...

• The CMakeLists.txt of a dependent target:

...
add_executable(example example.cpp)
target_link_libraries(example ${CONAN_LIBS} ${OpenMP_CXX_LIBRARIES})
...

Running Conan and CMake

• First, add new remote pointing to the repository:

conan remote add omaralvarez https://api.bintray.com/conan/omaralvarez/public-conan

• Change directory to the build location and run Conan installation:

conan install .. -s build_type=Release --build=missing

where the .. points to the project root at the parent directory.

• Run CMake:

cmake ..
