Brad King 2bbb1713de ENH: Clarify documentation of EXCLUDE_FROM_ALL
The add_subdirectory() command's EXCLUDE_FROM_ALL option does not
override inter-target dependencies.  This change clarifies the
documentation accordingly.

"Add a subdirectory to the build. The source_dir specifies the "
"directory in which the source CmakeLists.txt and code files are "
"located. If it is a relative "
"path it will be evaluated with respect to the current "
"directory (the typical usage), but it may also be an absolute path. "
"The binary_dir specifies the directory in which to place the output "
"files. If it is a relative path it will be evaluated with respect "
"to the current output directory, but it may also be an absolute "
"path. If binary_dir is not specified, the value of source_dir, "
"before expanding any relative path, will be used (the typical usage). "
"The CMakeLists.txt file in the specified source directory will "
"be processed immediately by CMake before processing in the current "
"input file continues beyond this command.\n"
"If the EXCLUDE_FROM_ALL argument is provided then targets in the "
"subdirectory will not be included in the ALL target of the parent "
"directory by default, and will be excluded from IDE project files. "
"Users must explicitly build targets in the subdirectory. "
"This is meant for use when the subdirectory contains a separate part "
"of the project that is useful but not necessary, such as a set of "
"examples. "
"Typically the subdirectory should contain its own project() command "
"invocation so that a full build system will be generated in the "
"subdirectory (such as a VS IDE solution file). "
"Note that inter-target dependencies supercede this exclusion. "
"If a target built by the parent project depends on a target in the "
"subdirectory, the dependee target will be included in the parent "
"project build system to satisfy the dependency."
