The tests-if-CYGWIN topic made a change to Tests/Testing/CMakeLists.txt
in code that the custom-command-generator-expressions topic moved to the
Tests/PerConfig/CMakeLists.txt file. Make the same change to the same
content in the new file. (Only a small part of the file moved so rename
detection did not do this automatically.)
Put the source files, build rules, and test scripts for these targets
under Tests/PerConfig and refer to it from Tests/Testing as a
subdirectory. The targets and scripts will be useful in other tests.
Commit "merge in changes for beos support" (2006-12-04) added a realpath
call for every directory parsed out of a PATH-style environment
variable. No reason was given in the commit message or comments.
The call incorrectly resolves symlinks in referenced paths. Remove it.
If BeOS support really needs it then it can be restored for that
platform with a full explanation.
The cmCustomCommandGenerator::GetCommand method completely replaces the
purpose of this method. Re-implement GetRealLocation inline at the only
remaining call site and remove it.
The Makefile, VS, and Xcode generators previously duplicated some custom
command line generation code. Factor this out into a separate class
cmCustomCommandGenerator shared by all generators.
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.
Imported targets do not themselves build, but we can follow dependencies
through them to find real targets. This allows imported targets to
depend on custom targets that provide the underlying files at build
time.
Commit 60cd72d0 (Cleaned up generation of symbolic rules, 2006-02-15)
incorrectly made these Makefile targets .PHONY even though the build
rule touches an actual file. Correct it so that the copy_f90_mod and
touch steps do not happen on every "make".
Commit 1a0c166 (Store direct dependencies in solutions for VS >= 8,
2010-08-20) disabled use of VS-specific global dependency analysis.
Avoid perfoming the analysis at all when it is not needed. This also
prevents creation of bogus and unused '_UTILITY' targets since they are
not needed for dependencies.
Previously the command
find_path(VAR DOC "")
would crash because the argument pre-processing removed the DOC ""
arguments but the rest of the parsing assumes at least 2 arguments.
Reject the call with an error instead.
