PntAndCnt cf4d981483 Set OpenSceneGraph_${component}_FOUND to TRUE for existing target.
Following statement will never set OpenSceneGraph_osgText_FOUND to TRUE:

```
FIND_PACKAGE(OpenSceneGraph REQUIRED COMPONENTS osgViewer osgText CONFIG)
```

It cause cmake failure, the error message is confusing:
```
Found package configuration file:

/usr/local/osg/gl2/lib/cmake/OpenSceneGraph/OpenSceneGraphConfig.cmake

but it set OpenSceneGraph_FOUND to FALSE so package "OpenSceneGraph" is
considered to be NOT FOUND.
```

I know one doesn't need to add osgText after osgViewer, but it should
not cause an error with confusing message.

# - Config file for the OpenSceneGraph package.
#
# For finding and loading OpenSceneGraph from your project, type:
#
# find_package(OpenSceneGraph [version] [COMPONENTS comp])
#
# This creates the following variables:
#
# OpenSceneGraph_LIBRARIES : All the libraries of all the requested components
# OPENSCENEGRAPH_LIBRARIES
#
# OpenSceneGraph_INCLUDE_DIRS : All the include directories of all the requested components
# OPENSCENEGRAPH_INCLUDE_DIRS
#
# OpenSceneGraph_FOUND : Set to true if all required components can be found
# OPENSCENEGRAPH_FOUND
#
# OpenSceneGraph_<comp>_FOUND : Set to true if this component was found
# OPENSCENEGRAPH_<COMP>_FOUND
#
# OSG_LIBRARY : The library for the core OSG component
# OSG_LIBRARIES
#
# OSG_INCLUDE_DIR : The include directory for the core OSG component
#
# <COMP>_LIBRARY : This is created for each requested component <comp>
# <COMP>_LIBRARIES and refers to the component's library
#
# <COMP>_INCLUDE_DIR : This is created for each requested component <comp>
# and refers to the component's include directory
################################################################################
#
# This config-file will also import the following targets:
#
# @PKG_NAMESPACE@::osg (for the core OSG library)
# @PKG_NAMESPACE@::<comp> (for each requested component library)
#
# Use target_link_libraries(tgt [PUBLIC|PRIVATE] @PKG_NAMESPACE@::<comp>)
# for each component that you want to link to.
#
# For convenience, this will also produce a variable
#
# OpenSceneGraph_TARGETS
#
# which will contain the targets of all the requested components.
