example

git clone https://github.com/52doho/vcpkg-vs-conan.git && \
cd vcpkg-vs-conan && \
./auto-build-run.sh

Steps to use vcpkg

1. install vcpkg

Prerequisites

• Windows 10, 8.1, 7, Linux, or MacOS
• Visual Studio 2015 Update 3 or newer (on Windows)
• Git
• gcc >= 7 or equivalent clang (on Linux)
• Optional: CMake 3.12.4

build vcpkg

git clone https://github.com/Microsoft/vcpkg.git && \
cd vcpkg && \
./bootstrap-vcpkg.sh && \
./vcpkg integrate install

be careful for building failed in centos

2. search & add library

./vcpkg search cpprestsdk
./vcpkg install cpprestsdk

(Only v2.10.16 is available. glog install failed in CentOS, success in Ubuntu)

3. update CMakeLists.txt

cmake_minimum_required(VERSION 3.5)
project(vcpkg-vs-conan)

set(CMAKE_CXX_STANDARD 11)

find_package(cpprestsdk CONFIG REQUIRED)
find_package(OpenCV CONFIG REQUIRED)
find_package(glog CONFIG REQUIRED)

add_executable(${PROJECT_NAME} main.cpp)

target_link_libraries(${PROJECT_NAME}
    cpprestsdk::cpprest
    ${OpenCV_LIBS}
    glog::glog
    )

4. build

cmake .. -DCMAKE_TOOLCHAIN_FILE=/path/to/vcpkg/scripts/buildsystems/vcpkg.cmake && \
make

Steps to use conan

1. install conan

CentOS

sudo yum install python36 python36-devel python36-setuptools && \
sudo easy_install-3.6 pip && \
sudo pip3 install conan

Ubuntu

sudo apt-get install python3.5 python3-pip && \
sudo pip3 install conan

conan remote add is https://api.bintray.com/conan/labviros/is
conan remote add lasote https://api.bintray.com/conan/lasote/conan-repo

2. search & add library

conan search cpprestsdk

add configs in conanfile.txt file:

[requires]
cpprestsdk/2.10.13@bincrafters/stable
glog/0.4.0@bincrafters/stable
opencv/3.4.3@conan/stable
faiss/1.6.3@jdai/stable

[options]
*:shared=True
gflags:nothreads=False
gflags:fPIC=True
gflags:namespace=google

[imports]
#bin, *.dll -> ./src/bin
#lib, *.dylib* -> ./src/bin
#lib, *.so* -> ./src/bin

[generators]
cmake

3. update CMakeLists.txt

cmake_minimum_required(VERSION 3.5)
project(vcpkg-vs-conan)

set(CMAKE_CXX_STANDARD 11)

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

link_libraries(
    ${CONAN_LIBS}
)

add_executable(${PROJECT_NAME} main.cpp)

4. build

conan install .. && \
cmake .. && \
make

creating conan package
