Since commit ad502502 (cmMakefile: Track configured files so we can
regenerate them, 2013-06-18) cmMakefile::ConfigureFile records the
configured file as an output file generated by CMake. The intention is
that for make and ninja we can re-run CMake when one of the files it
generates goes missing. However, files configured temporarily in
CMakeTmp directories by Check* modules do not live past the CMake
invocation.
We have to also track input files to the configure command. In theory
the input to a configure command could it self be a file that is going
to be deleted later (output from a custom command or configure_file).

Teach cmMakefile::FinalPass to stop tracking files that don't
exist after we are finished generation.
Commit 10a069b5 (Genex: Fix $<CONFIG> with IMPORTED targets and
multiple locations., 2013-07-15) changed the logic here to include
handling of the MAP_IMPORTED_CONFIG_<CONFIG> target property, but
it was buggy in several ways.
Uppercase the configs in all cases, and compare the mapped configs
with the parameter to the CONFIG genex, instead of with the key of
the mapping.
Ensure CMAKE_DATA_DIR, CMAKE_DOC_DIR, and CMAKE_MAN_DIR are always
relative paths in CMake code, and set defaults accordingly. Use the
install() command instead of install_files() and install_targets().
This is more modern and also avoids stripping of the first character
from user-specified destinations.
While at it, fix the default destinations reported in the bootstrap
help.
The MSBuild version for each Visual Studio generator isn't 4.0. With
Visual Studo 2013 the ToolsVersion moved from being tied to the .NET
framework and now has its own version number.
Follow-up to commit 4a015f77 (OpenBSD: Add paths for Tcl/Tk 8.4/8.5,
2012-12-03): those paths added for OpenBSD also work on other BSDs, some
of which are already using version 8.6 of Tcl/Tk.
Exclude Ninja and Xcode from the CMP0021 test
They do not behave the same as the makefile generator with
relative paths.
Don't overwrite the header file for in-source builds.
