Add CMAKETARGETS infrastructure for CMake packages 



The CMAKETARGETS infrastructure makes adding CMake-based packages to
Buildroot easy. It uses the same set of variables as the autotools
infrastructure, except for autoreconf and libtool stuff which is not
needed. Usage: just call CMAKETARGETS instead of AUTOTARGETS.

# 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 informations 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.

#

# CMAKETARGETS_INNER -- defines how the configuration, compilation and

# installation of a CMake package should be done, implements a few hooks to

# tune the build process and calls the generic package infrastructure to

# generate the necessary make targets

#

#  argument 1 is the lowercase package name

#  argument 2 is the uppercase package name, including an HOST_ prefix

#             for host packages

#  argument 3 is the uppercase package name, without the HOST_ prefix

#             for host packages

#  argument 4 is the package directory prefix

#  argument 5 is the type (target or host)
