+# CMake package infrastructure
+#
+# This file implements an infrastructure that eases development of
+# package .mk files for CMake packages. It should be used for all
+# packages that use CMake as their build system.
+#
+# See the Buildroot documentation for details on the usage of this
+# infrastructure
+#
+# In terms of implementation, this CMake infrastructure requires
+# the .mk file to only specify metadata information about the
+# package: name, version, download URL, etc.
+#
+# We still allow the package .mk file to override what the different
+# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
+# already defined, it is used as the list of commands to perform to
+# build the package, instead of the default CMake behaviour. The
+# package can also define some post operation hooks.
