  -l LOCKFILE, --lockfile LOCKFILE
                        Path to a lockfile. Use --lockfile="" to avoid

  -pr PROFILE, --profile PROFILE
                        Apply the specified profile. By default, or if
                        specifying -pr:h (--profile:host), it applies to the
                        host context. Use -pr:b (--profile:build) to specify
                        the build context, or -pr:a (--profile:all) to specify
                        both contexts at once
  -pr:b PROFILE_BUILD, --profile:build PROFILE_BUILD
  -pr:h PROFILE_HOST, --profile:host PROFILE_HOST
  -pr:a PROFILE_ALL, --profile:all PROFILE_ALL
  -o OPTIONS, --options OPTIONS
                        Apply the specified options. By default, or if
                        specifying -o:h (--options:host), it applies to the
                        host context. Use -o:b (--options:build) to specify
                        the build context, or -o:a (--options:all) to specify
                        both contexts at once. Example: -o pkg:with_qt=true
  -o:b OPTIONS_BUILD, --options:build OPTIONS_BUILD
  -o:h OPTIONS_HOST, --options:host OPTIONS_HOST
  -o:a OPTIONS_ALL, --options:all OPTIONS_ALL
  -s SETTINGS, --settings SETTINGS

                        specifying -s:h (--settings:host), it applies to the
                        host context. Use -s:b (--settings:build) to specify
                        the build context, or -s:a (--settings:all) to specify
                        both contexts at once. Example: -s compiler=gcc
  -s:b SETTINGS_BUILD, --settings:build SETTINGS_BUILD
  -s:h SETTINGS_HOST, --settings:host SETTINGS_HOST
  -s:a SETTINGS_ALL, --settings:all SETTINGS_ALL
  -c CONF, --conf CONF  Apply the specified conf. By default, or if specifying
                        -c:h (--conf:host), it applies to the host context.
                        Use -c:b (--conf:build) to specify the build context,
                        or -c:a (--conf:all) to specify both contexts at once.
                        Example: -c tools.cmake.cmaketoolchain:generator=Xcode
  -c:b CONF_BUILD, --conf:build CONF_BUILD
  -c:h CONF_HOST, --conf:host CONF_HOST
  -c:a CONF_ALL, --conf:all CONF_ALL

The conan export-pkg command creates a package binary directly from pre-compiled binaries in a user folder. This command can be useful in different cases:

• When creating a package for some closed source or pre-compiled binaries provided by a vendor. In this case, it is not necessary that the conanfile.py recipe contains a build() method, and providing the package() and package_info() method are enough to package those pre-compiled binaries. In this case the build_policy = "never" could make sense to indicate it is not possible to conan install --build=this_pkg, as it doesn’t know how to build from sources when it is a dependency.

• When testing some recipe locally in the local development flow, it can be used to quickly put the locally built binaries in the cache to make them available to other packages for testing, without needing to go through a full conan create that would be slower.

In general, it is expected that when conan export-pkg executes, the possible Conan dependencies that were necessary to build this package had already been installed via conan install, so it is not necessary to download dependencies at export-pkg time. But if for some reason this is not the case, the command defines --remote and --no-remote arguments, similar to other commands, as well as the --skip-binaries optimization that could save some time installing dependencies binaries if they are not strictly necessary for the current export-pkg. But this is the responsibility of the user, as it is possible that such binaries are actually necessary, for example, if a tool_requires = "cmake/x.y" is used and the package() method implements a cmake.install() call, this will definitely need the binaries for the dependencies installed in the current machine to execute.
