file: Add GENERATE command to produce files at generate time The idea is to write to a temp file which contains generator expressions, and at generate time, evaluate the generator expressions, and write the result to a file. Because executables on Windows are limited in the length of command line it is possible to use, it is common to write command line arguments to a file instead and specify the file as a source of arguments. This new FILE(GENERATE) subcommand allows the use of generator expressions to create such files so that they can be used with add_custom_command for example.

Tests: Activate tests accidentally excluded from Xcode The generator name is "Xcode", not "XCode". Fix this typo. Explicitly exclude the SubDirSpaces test on Xcode because it does not work. Also tell the RunCMake.File_Generate test when Xcode is not multi-config so it can exlcude the OutputConflict case. Inspired-by: Daniele E. Domenichelli <daniele.domenichelli@iit.it>

file(GENERATE): Evaluate early to allow generating source files The evaluation files must be known before cmTargetTraceDependencies attempts to find them, but we must actually generate the files after cmTargetTraceDependencies, as that can add to target SOURCES. The limitation is that the generated output name must not depend on the SOURCES of a target if the generated file is used by that target. Mark the output files as GENERATED so that trace dependencies does not expect them to already exist in the filesystem. Move the invokation of ForceLinkerLanguage in the Generate logic to after the generated file names are known. ForceLinkerLanguage tries to determine the sources of a target (in order to determine an already-known language) and otherwise fails to get information about the generated file. Test that the output of file(GENERATE) can be used as a target source file and that accessing the target SOURCES in the name of the output file is an error. Accessing the TARGET_OBJECTS would be a similar error if it was legal to use that generator expression in this context. That is not currently possible and is a different error condition, so test the current error output as a reminder to change the expected output if that becomes possible in the future. Test that generated rule files resulting from cmTargetTraceDependencies appear in the SOURCES generated in the output file.
