# Automate-VCPKG by Andre Taulien
# ===============================
#
# Project Repository: https://github.com/REGoth-project/Automate-VCPKG
# License ..........: MIT, see end of file.
#
# Based on: https://github.com/sutambe/cpptruths/blob/vcpkg_cmake_blog/cpp0x/vcpkg_test/CMakeLists.txt
#
#
# While [Vcpkg](https://github.com/microsoft/vcpkg) on it's own is awesome, it does add
# a little bit of complexity to getting a project to build. Even more if the one trying
# to compile your application is not too fond of the commandline. Additionally, CMake
# commands tend to get rather long with the toolchain path.
#
# To keep things simple for new users who just want to get the project to build, this
# script offers a solution.
#
# Lets assume your main `CMakelists.txt` looks something like this:
#
# cmake_minimum_required (VERSION 3.12.0)
# project (MyProject)
#
# add_executable(MyExecutable main.c)
#
# To integrate Vcpkg into that `CMakelists.txt`, simple put the following lines before the
# call to `project(MyProject)`:
#
# include(cmake/automate-vcpkg.cmake)
#
# vcpkg_bootstrap()
# vcpkg_install_packages(libsquish physfs)
#
# The call to `vcpkg_bootstrap()` will clone the official Vcpkg repository and bootstrap it.
# If it detected an existing environment variable defining a valid `VCPKG_ROOT`, it will
# update the existing installation of Vcpkg.
#
# Arguments to `vcpkg_install_packages()` are the packages you want to install using Vcpkg.
#
# If you want to keep the possibility for users to chose their own copy of Vcpkg, you can
# simply not run the code snippet mentioned above, something like this will work:
#
# option(SKIP_AUTOMATE_VCPKG "When ON, you will need to built the packages
# required by MyProject on your own or supply your own vcpkg toolchain.")
#
# if (NOT SKIP_AUTOMATE_VCPKG)
# include(cmake/automate-vcpkg.cmake)
#
# vcpkg_bootstrap()
# vcpkg_install_packages(libsquish physfs)
# endif()
#
# Then, the user has to supply the packages on their own, be it through Vcpkg or manually
# specifying their locations.
