[cmake-developers] find_program() not using PATH on Windows?

[Robert Dailey]

Thanks for the feedback Brad, as always. Really appreciate your
continued help. Sorry for continuing the discussion on the dev list.

To close out the discussion just wanted to share (for others that may
run into this issue) that I went ahead and just added this line to my
root CMakeLists.txt file:

set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)

This at least disables the root path for programs. I didn't add it to
the toolchain itself since I don't know the impact of doing it, nor do
I really care to support it. I'm slowly trying to move away from
Crystax at my workplace in favor of official NDK since that has built
in support in CMake and also is run a little better (Crystax has been
a fat mess to use; we originally only chose to use it for the prebuilt
libraries, but not worth it)

Thanks again!!
