Vcpkg

https://vcpkg.io/{:target="_blank"} Vcpkg helps you manage C and C++ libraries on Windows, Linux and MacOS. This tool and ecosystem are constantly evolving, and we always appreciate contributions! Introduction https://github.com/microsoft/vcpkg{:target="_blank"} MS에서 만든 C++ Library Package 관리 (Cross Platform) Vcpkg install Git 이 필요하고, bootstrap-vcpkg 실행으로 필요한 툴을 다운로드(빌드)하는 작업을 수행 vcpkg.exe 생성 $ git clone https://github.com/microsoft/vcpkg $ cd vcpkg # windows $ bootstrap-vcpkg.bat # linux $ ./bootstrap-vcpkg.sh Package search & install triplet : Target configuration set 설치시 triplet 을 지정하지 않으면 설치되어 있는 기본 C++ Toolset 으로 지정 Windows의 경우 x86-windows default 주요 Triplet list vcpkg help triplet $ vcpkg help triplet Available architecture triplets VCPKG built-in triplets: ... x64-windows-static x64-windows x86-windows ...
