The setlocal/endlocal and errorlevel pattern added by commit 06fcbc47
(VS10: Fix working directory of consecutive custom commands, 2011-04-08)
does not work well in VS 7.1. Restore the original behavior for VS
versions that do not need the new behavior.
The VS 10 msbuild tool uses a single command shell to invoke all the
custom command scripts in a project. Isolate the environment and
working directory of custom commands using setlocal/endlocal. The
form of each command is
set errlev=
setlocal
cd c:\work\dir
if %errorlevel% neq 0 goto :cmEnd
c:
if %errorlevel% neq 0 goto :cmEnd
command1 ...
if %errorlevel% neq 0 goto :cmEnd
...
commandN ...
if %errorlevel% neq 0 goto :cmEnd
:cmEnd
endlocal & set errlev=%errorlevel%
if %errlev% neq 0 goto :VCEnd
so that all changes to the environment and working directory are
isolated within the script and the return code is preserved.
The Intel Fortran plugin forgets to create the output directory into
which it will write a DLL's import library. Utilize the fix added by
commit f4b3bdc6 (Create an exe's implib output dir for VS, 2009-06-15)
and generalized by commit 764ac980 (Generalize exe implib dir creation
for VS, 2009-06-16). Create a pre-link rule to make the directory.
In VS9 and previous versions, :VCReportError is the goto label
to jump to after a failed custom command. It stops the build
before it tries to go any further.
In VS10, :VCEnd is the correct label to use.
Create a method in the VS generators to provide the correct
line of script to use for each version of Visual Studio.
For more internal details, search for VCEnd in the
C:\Program Files\MSBuild directory.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
Until now the VS 10 generator did no Windows command-line escaping and
just did XML escapes. This commit teaches the generator to use the same
command-line escape addition code used by other generators. The script
construction method cmLocalVisualStudioGenerator::ConstructScript need
not do XML escapes. Each VS generator version adds the XML escapes
necessary for that version.
In VS 7,8,9 executable targets we generate a build event to create the
output directory for the import library in case the executable marks
symbols with dllexport (VS forgets to create this directory). This
generalizes computation of the custom command line to support future use
with other VS versions.
add_custom_target() as COMMAND, and cmake will recognize them and replace
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
