Hi,
the attached patch adds support for the CTEST_INITIAL_CACHE variable when
using new-style ctest commands.
Now ctest_configure() checks the CTEST_INITIAL_CACHE variable and if it is not
empty, AND there is no CMakeCache.txt yet, it writes the initial
CMakeCache.txt
I had a look at the code of the old-style ctest script, it seems there any
existing CMakeCache.txt is overwritten if CTEST_INITIAL_CACHE is set. Is this
correct ? Is this behaviour also wanted for the new-style commands ?
I think it is not necessary, because if I want to have a fresh cmake run, I
can use ctest_empty_binary_directory() before, then I will also get the
initial cache again.
What do you think ?
Ok to commit ?
I am not sure I like the idea. The old style ctest was declarative in
nature. The new one is procedural. I am not sure I like magic global
variables affecting commands. A better way to do this would be to add
an optional argument to ctest_configure that allows an initial cache to
be passed into the function.
