[jira] [Comment Edited] (ARROW-11580) [C++] Add CMake option
ARROW_DEPENDENCY_SOURCE=VCPKG
[ https://issues.apache.org/jira/browse/ARROW-11580?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17286708#comment-17286708 ]

------------------------------------------------------------
Finding where vcpkg is installed and where it has installed packages is not as straightforward as with conda or brew.
If you install vcpkg as per the docs, it does not add the vcpkg install directory to the path, and it does not set any environment variables that help you to find it. However when you run {{vcpkg integrate install}}, it creates a plain text file {{vcpkg.path.txt}} containing the path of the install directory. On Mac and Linux, this file is placed in {{$HOME/.vcpkg}}. On Windows, it's placed in {{%LOCALAPPDATA%\vcpkg}}. Knowing the install directory allows us to set the required CMake variable {{CMAKE_TOOLCHAIN_FILE}}.
vcpkg also puts some other files in that same directory, but the details are poorly documented and it's sometimes necessary to read the vcpkg source code in [https://github.com/microsoft/vcpkg-tool] to figure out what it's doing.
