No, those variables are empty. Here's my configuration

I think there is... another proof:

Also, does this happen with a very simple one line cmakelist.txt file?
add_library(foo.cxx)
(of course you will have to create an empty foo.cxx)
I always test with a clean CMakeCache.txt (i.e., without it), and don't
even add a lib

For sure. Here's the setup:
test.c:
int main() {}
CMakeLists.txt:
list(APPEND CMAKE_C_FLAGS -Wall)
add_executable(test test.c)
when we run make, we have:
gcc: no input files
/bin/sh: -Wall: not found

I've managed to debug and correct this 'bug'. The bug report is at:
http://www.cmake.org/Bug/view.php?id=6167
I really think that compiler flags should be treated like a list of
flags instead of a string because this way, IMHO, it's easier to deal
with space in flag parameters etc, to add a flag t

The same happens with cmake-2.4.7
So it does! I just checked on a linux system...
So, lets get back to the original problem...

It's malignant from the standpoint of IF. CMAKE_C_FLAGS is being
initialized to a nonempty string. That means
if(CMAKE_C_FLAGS) will succeed. Should file a bug or fix it.
