In CMake 2.0, the install was changed from using install.sh to being implemented 
as part of cmake.  As a result, cmake install is now faster, and actually
works on systems that do not have /bin/sh like windows without cygwin or msys.
A side effect of that is that msys paths are not recognized by cmake as they
were by the /bin/sh used in 1.8.   So, to explain your 1,2, and 3:

1. install.sh used msys /bin/sh and knew about msys paths.

2. Since it is looking in ../, cmake is actually finding a path, and using a windows path,
since that is the native paths for the windows build of cmake. If you changed
it to /usr/bin/wx or some other full path with /, cmake would not find it at all.

3. Msys is actually modifying the arguments that are coming into cmake!
It took a while to track down, but I found that 
cmake -DCMAKE_INSTALL_PREFIX:PATH="/usr/local"
sets argv[1] to -DCMAKE_INSTALL_PREFIX:PATH=C:/msys/1.0/local
I would not expect that, but that is what it did.

I am not sure exactly what to do, other than say that is how it works
with MSYS.
