 use Env qw( @PATH );
 
 unshift @PATH, Alien::cmake3->bin_dir;
 system 'cmake', ...;

From alienfile

 use alienfile;
 
 share {
   # Build::CMake plugin pulls in Alien::cmake3 automatically
   plugin 'Build::CMake';
   build [
     # this is the default build step, if you do not specify one.
     [ '%{cmake3}', -G => '%{cmake_generator}', '-DCMAKE_POSITION_INDEPENDENT_CODE:BOOL=true', '-DCMAKE_INSTALL_PREFIX:PATH=%{.install.prefix}', '.' ],
     '%{make}',
     '%{make} install',
   ];
 };

Version

version 0.10

Overview

This Alien distribution provides an external dependency on the build tool "cmake" version 3.x.x. "cmake" is a popular alternative to autoconf.

Methods

bin_dir

 my @dirs = Alien::cmake3->bin_dir;

List of directories that need to be added to the "PATH" in order for "cmake" to work.

exe

 my $exe = Alien::cmake3->exe;

The name of the "cmake" executable.

Helpers

cmake3

 %{cmake3}

The name of the "cmake" executable.

Environment

ALIEN_INSTALL_TYPE

This is the normal Alien::Build environment variable and you can set it to one of "share", "system" or "default".

ALIEN_CMAKE_FROM_SOURCE

If set to true, and if a share install is attempted, Alien::cmake3 will not try a binary share install (even if available), and instead a source share install.

Caveats

If you do not have a system "cmake" version 3.x.x available, then a share install will be attempted.

Binary share installs are attempted on platforms for which the latest version of "cmake" are provided. As of this writing, this includes: Windows (32/64 bit), macOS (intel/arm universal) and Linux (intel/arm 64 bit). No checks are made to ensure that your platform is supported by this binary installs. Typically the same versions supported by the operating system vendor and supported by "cmake", so that should not be a problem. If you are using an operating system not supported by its vendor Please Stop That, this is almost certainly a security vulnerability.

That said if you really do need Alien::cmake3 on an unsupported system, you have some options:

Install system version of "cmake"

If you can find an older version of "cmake" 3.x.x that is supported by your operating system.

Force a source code install

Set the "ALIEN_CMAKE_FROM_SOURCE" environment variable to a true value to build a share install from source.

Source share installs are attempted on platforms for which the latest version of "cmake" are not available, like the various flavours of *BSD. This may not be ideal, and if you can install a system version of "cmake" it may work better.
