Easiest is to look under the qgis/cmake dir and look at the examples
we have already created. Please note that I spent quite a bit of time
making a unified way to set dependencies using a $LIB_DIR environment
variable. In theory it should work for your msys environment and you
should need to do nothing more than do:

export LIB_DIR=/usr/local (or wherever you compiled all your dependencies to)
ccmake [options you fancy] ..
make install

For me it will be first prize if you can follow this paradigm of
setting a single LIB_DIR environment var to find all deps, though I
realise that may not work in all cases.

If you really cant see a way forward with that, I suggest adding msys
specific paths for your standard msys deps bundle into each
cmake/Find<foo>.cmake rule - just open a couple of files with a text
editor, the format is quite simple.
