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.
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.

These mainly come from the command line or manual entries in the
CMakeCache.txt file. We want to stop at the first '=' because this is
what is most likely to have been meant. The variable can be quoted if
the '=' is intended.
Caveat: What if one wants both '"' and '=' in a variable name?
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.
