# Passing of variables to vcpkg
#
# vcpkg runs cmake scripts in an isolated environment, see this for details:
# https://github.com/Microsoft/vcpkg/issues/3712
#
# Here's how this works and how we work around this issue:
#
# 1. This file (CMakeLists.txt) runs first and is authoritative. It is the one
# that reads the environment, sets variables and sets a default value.
# 2. It writes the contents of the variables to
# $CMAKE_CURRENT_BINARY_DIR/_env/$VARNAME
# 3. hifi_vcpkg.py takes the _env directory, and copies it to the vcpkg dir.
# This solves the issue of CMakeLists.txt not knowing where the vcpkg dir is.
# 4. cmake/ports/*/portfile.cmake does know where the vcpkg dir is, and can
# read the _env that was copied there to obtain the variable's name.
#
# To ensure no old data could be accidentally read, the _env directories are
# deleted on each execution and fully recreated.
# Ensure nothing is kept from any previous run
