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.
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.
Run cmparseMSBuildXML.py on cl.xml, lib.xml, and link.xml to generate
our flag tables:
python cmparseMSBuildXML.py -x ".../MSBuild/Microsoft.Cpp/v4.0/V110/1033/cl.xml" > cmVS11CLFlagTable.h
python cmparseMSBuildXML.py -x ".../MSBuild/Microsoft.Cpp/v4.0/V110/1033/lib.xml" > cmVS11LibFlagTable.h
python cmparseMSBuildXML.py -x ".../MSBuild/Microsoft.Cpp/v4.0/V110/1033/link.xml" > cmVS11LinkFlagTable.h
Fix up the declaration names at the top of each file. Finally, teach
cmVisualStudio10TargetGenerator to select the version of the table
matching the version of VS.
In VS 11 the WindowsAppContainer element enabled by the
VS_WINRT_EXTENSIONS property activates precompiled header support
automatically if no PrecompiledHeader setting is specified. For VS 10 and
11 set PrecompiledHeader to "NotUsing" explicitly by default unless
overridden by a project-specified flag.

Commit 4be67837 (read less from version headers into variables,
2012-08-19) switched from file(READ) and string(REGEX MATCHALL) to just
file(STRINGS) to extract the list of resource <file> entries. However,
the latter extracts entire lines that match the regex, not just the part
that matches the regex, so the subsequent string(REGEX REPLACE) fails to
match and replace anything. Return to the original parsing logic but
replace file(READ) with file(STRINGS) to load a minimal part of the file
before using string(REGEX MATCHALL) as before.
Because the main file for the dummy-executable and the actual compile
test were both called main.cpp, they were overwriting each other during
in-source builds.
Since commit 9e01aefd (VS: Add support for WinRT project properties,
2012-02-03) CMake generates for VS 11 projects the 'Immersive' element
for the VS_WINRT_EXTENSIONS target property. That was based on the VS
11 preview version. The final version renamed the element to
'WindowsAppContainer', so generate that instead.

Otherwise, CTEST_USE_LAUNCHERS can be set to true in a driving ctest
script, and everything looks like it would work and reports 0 build errors,
but actually there can be any amount of errors and they are just not reported.
By adding this check cmake now errors out if CTEST_USE_LAUNCHERS is enabled, but
the RULE properties are not set, which would lead to a not-working ctest run.

Added a new CUDA variable for specifying the CUDA_HOST_COMPILER. This will allow users to
be able to specify which host compiler to use for invoking NVCC with. By default it will
use the compiler used for host compilation. This is convenient for when you want to
specify a different compiler than the default compiler. You end up using the same
compiler for both the NVCC compilation and the host compilation instead of using the
default compiler in the path for NVCC.
There is no need to do so. Be consistent with include directories and
ensure uniqueness.
This requires changing the API of the cmLocalGenerator::AppendDefines
method, and changing the generators to match.
The test unfortunately can't test for uniqueness, but it at least verifies
that nothing gets lost.
