Alien::Build::Plugin::Probe::Vcpkg - Probe for system libraries using Vcpkg


version 2.80


 use alienfile;
 plugin 'Probe::Vcpkg' => 'libffi';


This plugin probe can be used to find "system" packages using Microsoft's Vcpkg package manager for Visual C++ builds of Perl. Vcpkg is a package manager for Visual C++ that includes a number of open source packages. Although Vcpkg does also support Linux and macOS, this plugin does not support finding Vcpkg packages on those platforms. For more details on Vcpkg, see the project github page here:

Here is the quick start guide for getting Alien::Build to work with Vpkg:

 # install Vcpkg
 C:\> git clone
 C:\> cd vcpkg
 C:\vcpkg> .\bootstrap-vcpkg.bat
 C:\vcpkg> .\vcpkg integrate install
 # update PATH to include the bin directory
 # so that .DLL files can be found by Perl
 C:\vcpkg> path c:\vcpkg\installed\x64-windows\bin;%PATH%
 # install the packages that you want
 C:\vcpkg> .\vcpkg install libffi
 # install the alien that uses it
 C:\vcpkg> cpanm Alien::FFI

If you are using 32 bit build of Perl, then substitute x86-windows for x64-windows. If you do not want to add the bin directory to the PATH, then you can use x64-windows-static instead, which will provide static libraries. (As of this writing static libraries for 32 bit Windows are not available). The main downside to using x64-windows-static is that Aliens that require dynamic libraries for FFI will not be installable.

If you do not want to install Vcpkg user wide (the integrate install command above), then you can use the PERL_WIN32_VCPKG_ROOT environment variable instead:

 # install Vcpkg
 C:\> git clone
 C:\> cd vcpkg
 C:\vcpkg> .\bootstrap-vcpkg.bat
 C:\vcpkg> set PERL_WIN32_VCPKG_ROOT=c:\vcpkg



Specifies the name of the Vcpkg. This should not be used with the lib property below, choose only one.

This is the default property, so these two are equivalent:

 plugin 'Probe::Vcpkg' => (name => 'foo');


 plugin 'Probe::Vcpkg' => 'foo';


Specifies the list of libraries that make up the Vcpkg. This should not be used with the name property above, choose only one. Note that using this detection method, the version number of the package will not be automatically determined (since multiple packages could potentially make up the list of libraries), so you need to determine the version number another way if you need it.

This must be an array reference. Do not include the .lib extension.

 plugin 'Probe::Vcpkg' => (lib => ['foo','bar']);


Specifies an alternate ffi_name for finding dynamic libraries.
