SYNOPSIS

12       From Perl:
13
14        use Alien::cmake3;
15        use Env qw( @PATH );
16
17        unshift @PATH, Alien::cmake3->bin_dir;
18        system 'cmake', ...;
19
20       From alienfile
21
22        use alienfile;
23
24        share {
25          # Build::CMake plugin pulls in Alien::cmake3 automatically
26          plugin 'Build::CMake';
27          build [
28            # this is the default build step, if you do not specify one.
29            [ '%{cmake3}', -G => '%{cmake_generator}', '-DCMAKE_POSITION_INDEPENDENT_CODE:BOOL=true', '-DCMAKE_INSTALL_PREFIX:PATH=%{.install.prefix}', '.' ],
30            '%{make}',
31            '%{make} install',
32          ];
33        };
34

DESCRIPTION

36       This Alien distribution provides an external dependency on the build
37       tool "cmake" version 3.0.0 or better.  "cmake" is a popular alternative
38       to autoconf.
39

45       "cmake" to work.
46
47   exe
48        my $exe = Alien::cmake3->exe;

SEE ALSO

59       Alien::Build::Plugin::Build::CMake
60           Alien::Build plugin for "cmake"  This will automatically pull in
61           Alien::cmake3 if you need it.
62
63       Alien::CMake
64           This is an older distribution that provides an alienized "cmake".
65           It is different in these ways:
66
67           Alien::cmake3 is based on alienfile and Alien::Build
68               It integrates better with Aliens that are based on that
69               technology.
70
71           Alien::cmake3 will provide version 3.0.0 or better
72               Alien::CMake will provide 2.x.x on some platforms where more
73               recent binaries are not available.
74
75           Alien::cmake3 will install on platforms where there is no system
76           "cmake" and no binary "cmake" provided by cmake.org
77               It does this by building "cmake" from source.
78
79           Alien::cmake3 is preferred
80               In the opinion of the maintainer of both Alien::cmake3 and
81               Alien::CMake for these reasons.
82

ENVIRONMENT

84       ALIEN_INSTALL_TYPE
85           This is the normal Alien::Build environment variable and you can
86           set it to one of "share", "system" or "default".
87
88       ALIEN_CMAKE_FROM_SOURCE
89           If set to true, and if a share install is attempted, Alien::cmake3
90           will not try a binary share install (even if available), and
91           instead a source share install.
92

CAVEATS

94       If you do not have a system "cmake" of at least 3.0.0 available, then a
95       share install will be attempted.
96
97       Binary share installs are attempted on platforms for which the latest
98       version of "cmake" are provided.  As of this writing, this includes:
99       Windows (32/64 bit), macOS (intel/arm universal) and Linux (intel/arm
100       64 bit).  No checks are made to ensure that your platform is supported
101       by this binary installs.  Typically the same versions supported by the
102       operating system vendor and supported by "cmake", so that should not be
103       a problem.  If you are using an operating system not supported by its
104       vendor Please Stop That, this is almost certainly a security
105       vulnerability.
106
107       That said if you really do need Alien::cmake3 on an unsupported system,
108       you have some options:
109
110       Install system version of "cmake"
111           If you can find an older version better than 3.0.0 that is
112           supported by your operating system.
113
114       Force a source code install
115           Set the "ALIEN_CMAKE_FROM_SOURCE" environment variable to a true
116           value to build a share install from source.
117
118       Source share installs are attempted on platforms for which the latest
119       version of "cmake" are not available, like the various flavours of
120       *BSD.  This may not be ideal, and if you can install a system version
121       of "cmake" it may work better.
