# Generate and install examples.

# This is boilerplate code for generating a set of executables, one per
# .cpp file in an "examples" subdirectory. 
#
# For IDEs that can deal with PROJECT_LABEL properties (at least
# Visual Studio) the projects for building each of these adhoc
# executables will be labeled "Example - TheExampleName" if a file
# TheExampleName.cpp is found in this directory.
#
# We check the BUILD_TESTING_{SHARED,STATIC} variables to determine
# whether to build dynamically linked, statically linked, or both
# versions of the executable.
