When a language is not enabled at the top level of a project but is
enabled in multiple disjoint subdirectories we should re-use the
CMake<lang>Compiler.cmake file from the first directory.  Load the file
whenever it exists and is not left from a different version of CMake.

Configure a hand-generated Visual Studio project to build the compiler id
source file since we cannot run the compiler command-line tool directly.
Add a post-build command to print out the full path to the compiler tool.
Parse the full path to the compiler tool from the build output.

When the VS 10 generator selects a non-default PlatformToolset to
specify for MSBuild, report the selected name in this variable.

Configure a hand-generated Xcode project to build the compiler id source
file since we cannot run the compiler command-line tool directly.  Add a
post-build shell script phase to print out the compiler toolset build
setting.  Run xcodebuild to compile the identification binary.  Parse
the full path to the compiler tool from the xcodebuild output.

Teach CMAKE_DETERMINE_COMPILER_ID to check for variable
CMAKE_${lang}_COMPILER_ID_TOOL after CMAKE_DETERMINE_COMPILER_ID_BUILD
to use as CMAKE_${lang}_COMPILER since it will not be known until after
the IDE runs.

In CMAKE_DETERMINE_COMPILER_ID_BUILD prepare a cascading "if" so we can
use a generator-specific method to compile the identification source
file.  Leave "if(0)" as a placeholder for now and put the direct
compiler invocation in "else()".  After running the compiler to build
the compiler identification source we file(GLOB) the list of output
files as candidates for extracting the compiler information.  An IDE may
create directories, so exclude exclude directories from this list.

Re-organize CMakeDetermine(C|CXX|Fortran)Compiler.cmake to search for
the compiler command-line tool only under generators for which it makes
sense.  For the Visual Studio generators we do not expect to find the
compiler tool from the environment, nor would we use the result anyway.

Furthermore, set CMAKE_${lang}_COMPILER_ID_TEST_FLAGS only when it has a
chance to be used.  Extract _CMAKE_TOOLCHAIN_LOCATION from the compiler
path after running the compiler id step so in the future that step can
help find the path to the compiler.

Since commit 77543bde (Convert CMake-language commands to lower case,
2012-08-13) the CMakeVersion.cmake file contains lower-case 'set'
commands.  Teach CMakeVersion.bash to replace the lower-case name
instead of the old upper-case 'SET'.

After conversion of Modules .cmake files to lower case the
FAIL_REGULAR_EXPRESSION for this test matched warnings in modules other
than the test line itself.  Make the pass and fail regular expressions
specific to the file containing the lines they are testing.

This was missed by commit 7bbaa428 (Remove trailing whitespace from most
CMake and C/C++ code, 2012-08-13) which only removed trailing spaces,
not TABs.

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-' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed

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'

3a17311b Release: Temporarily exclude ExternalProject test on cygwin

Since commit c198730b (Detect Watcom compiler version with its id,
2011-12-07) the CMAKE_(C|CXX)_COMPILER_VERSION variables are set for the
Watcom compiler.  Use these in Windows-wcl386.cmake to set the old
WATCOM1* version variables.  This avoids using the old EXECUTE_PROCESS
command which failed due to extra quotes anyway.

Multiple versions of Xcode may be installed in different locations.
Run "xcode-select --print-path" to detect the active Xcode location
and parse its Contents/version.plist file.  Note that the Xcode.app
directory name may vary in developer versions.
