Hi,
Does CMake performs arithmetic expansion?
Do we have to use an external tool? (like bc, or expr)
I don't find anything about it on the bug tracker.
I would be fantastic to be able to write something like this:
SET(Foo 2)
SET(Bar $EVAL{0x101000 + ${Foo}})
To avoid complexity growth of the parser but still be
platform-independant, maybe you could add a command available with
CMake -E.
==> CMAKE -E EVAL "0x101000 + ${Foo}"
The worst case would be a module FindBc.cmake which provides a macro Bc_EVAL
my 2 cents.
