Peter Collingbourne fe5d6e8c0f Add USES_TERMINAL option for custom commands
Teach the add_custom_command and add_custom_target commands a new
USES_TERMINAL option.  Use it to tell the generator to give the command
direct access to the terminal if possible.

Stephen Kelly c4af46b444 add_custom_command: Normalize OUTPUT and DEPENDS paths.
While tracing dependencies of a target, cmTargetTraceDependencies
follows sources by full path to determine if the source is to be
produced by a custom command.  Commit 4959f341 (cmSourceFileLocation:
Collapse full path for directory comparisons., 2014-03-27) changed
the storage of target sources to be in the form of a normalized
path instead of an unnormalized path.

The path is followed by looking it up in a mapping via
cmMakefile::GetSourceFileWithOutput to acquire an appropriate
cmSourceFile.  The mapping is populated with the OUTPUT components
of add_custom_command invocations, however it is populated with
unnormalized paths.  This means that the tracing logic does not
find appropriate cmSourceFiles, and does not generate appropriate
build rules for the generated sources.

Normalize the paths in the OUTPUT components of add_custom_command
to resolve this.

The paths in the DEPENDS component of add_custom_command are also
not normalized, leading to the same problem again.  Normalize the
depends paths after generator evaluation and expansion.

Stephen Kelly bbffccca42 add_custom_command: Evaluate generator expressions in DEPENDS
Rely on evaluation in cmCustomCommandGenerator for the generators.

When tracing target dependencies, depend on the union of dependencies
for all configurations.

Daniele E. Domenichelli 15610bb5b1 Drop use of configure_file IMMEDIATE option
Since commit 7d47c693 (Drop compatibility with CMake < 2.4, 2013-10-08)
we no longer need to use the configure_file IMMEDIATE option to support
compatibility modes less than 2.0.

Robert Maynard 88d27ad014 Add a test to expose a bug with add_custom_command and ninja.
Ninja Generator is unable to handle an add_custom_command having
a dependency that is generated at build time by a previous target.

Kitware Robot 9db3116226 Remove CMake-language block-end command arguments
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block.  This is no longer the preferred style.

Run the following shell code:

for c in else endif endforeach endfunction endmacro endwhile; do
    echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |

Kitware Robot 77543bde41 Convert CMake-language commands to lower case
Ancient CMake versions required upper-case commands.  Later command
names became case-insensitive.  Now the preferred style is lower-case.

Run the following shell code:

cmake --help-command-list |
grep -v "cmake version" |
while read c; do
    echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
xargs -0 sed -i -f convert.sed &&

Kitware Robot 7bbaa4283d Remove trailing whitespace from most CMake and C/C++ code
Our Git commit hooks disallow modification or addition of lines with
trailing whitespace.  Wipe out all remnants of trailing whitespace
everywhere except third-party code.

git ls-files -z -- \

 '*.c' '*.cmake' '*.cpp' '*.cxx' \
 '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \

Brad King 128605054a Normalize slashes of add_custom_(command|target) DEPENDS (#11973)
All commands accepting file paths should normalize the slashes so that
the string-represented names can be compared reliably.  The commands
add_library and add_executable have done this for years.  We taught
add_custom_command to normalize its OUTPUT names in commit a75a0a14
(Normalize add_custom_command OUTPUT names, 2010-12-15).  We handled a
special case of the DEPENDS option in commit 7befc007 (Handle trailing
slashes on add_custom_command DEPENDS, 2011-01-26).

Teach both add_custom_command and add_custom_target to normalize slashes
of DEPENDS files up front.  This approach subsumes the above-mentioned
special case so remove the one line added for it but keep its test.
Extend the CustomCommand test to check that slash count mismatches
between custom command OUTPUT and DEPENDS can still be linked correctly.

Brad King f0cdb6001b Introduce "generator expression" syntax to custom commands (#11209)
Evaluate in the COMMAND arguments of custom commands the generator
expression syntax introduced in commit d2e1f2b4 (Introduce "generator
expressions" to add_test, 2009-08-11).  These expressions have a syntax
like $<TARGET_FILE:mytarget> and are evaluated during build system
generation.  This syntax allows per-configuration target output files to
be referenced in custom command lines.

Brad King a75a0a1448 Normalize add_custom_command OUTPUT names (#10485)
Previously the OUTPUT arguments of add_custom_command were not
slash-normalized but those of add_library and add_executable were.
This caused the example

  add_custom_command(OUTPUT a//b.c ...)
  add_library(... a//b.c ...)

to fail at build time with "no rule to make a/b.c".  Fix this and modify
the CustomCommand test to try it.

Brad King ced1d5eccd Skip file-level dependencies on custom targets (#11332)
A custom command may name a target created by add_custom_target in its
DEPENDS field.  Treat this case as a target-level dependency only since
a custom target provides no standard file on which to add a file-level
dependency.

David Cole a798bb7074 Avoid CustomCommand test failure on VS71 (#9963)
Test still failing on dash1.kitware. Give up on testing
the new arg on MSVC71. Test it with newer nmakes instead.
All other dashboards are fine with -DPATH=c:/posix/path
as the first arg, so keep it except when MSVC71 is true.

David Cole 9b4ab06c2c Avoid CustomCommand test failure on VS71 (#9963)
The new first arg in the test is the critical one
to prove that the new NMake specific code works.
The additional colons in the middle of the arg
stream work fine everywhere else, but not on
dash1.kitware with Visual Studio 7.1. Just avoid
the failure for now by removing the unnecessary
new args from the test.

David Cole 9d2e6489bf No extra spaces in CustomCommand test (#9963)
The nightly dashboard showed that the following
platforms had difficulties dealing with "bin dir"
and/or "check command line" as directory and
file names:

  AIX
  Borland 5.5, 5.6 and 5.8
  IRIX
  NMake 6.0
  OpenBSD
  VS 7.1
  Watcom

Re-visit later, after the release, to use spaces
in the bin dir and in the target name where possible.

David Cole 269a4b876a Enable calling commands with : in argv[1] (#9963)
The solution seems hackish, but it works: for
NMake only, prepend a no-op command before each
real command that begins with ".

This is really a work-around for an NMake problem.
When a command begins with ", nmake truncates the
first argument to the command after the first :
in that arg. It has a parsing problem.

Workaround..., hackish..., but it should solve
the issue for #9963 and its related friends.

Also, modify the CustomCommand test to replicate
the problem reported in issue #9963. Before the
NMake specific code change, the test failed.
Now, it passes. Ahhhhhh.

Brad King 0a83aa6f57 BUG: Fix windows command line escape for empty arg

build, but will show up in the IDE project files for convenient editing.

2.6.1.

Brad King bed3ac8741 ENH: Remove SKIP_RULE_DEPENDS option from add_custom_command()
- Option was recently added but never released.
  - Custom commands no longer depend on build.make so we do
    not need the option.
  - Rule hashes now take care of rebuilding when rules change
    so the dependency is not needed.

Brad King 600e5e274e ENH: Add SKIP_RULE_DEPENDS option for add_custom_command()
- Allows make rules to be created with no dependencies.
  - Such rules will not re-run even if the commands themselves change.
  - Useful to create rules that run only if the output is missing.

Brad King 0f4ad19ef8 ENH: Re-arranged code to test adding a custom command to generate a source file after the file has been added to a target. This is supported by the current implementation because of the use of source lists in the target implementation.

Alexander Neundorf 7f11536704 ENH: now target names can be used in add_custom_command() and

them with the actual output path of these executables. Also the dependency
will be added automatically. Test included.
ENH: moved TraceVSDependencies() to the end of GlobalGenerator::Configure(),
so it is done now in one central place
