Check a program existence in PATH

I'm running batch scripts (usually from Visual Studio) and want to check that some program available through the PATH and if not - then show a message. Simple file checking like 

if exist mingw32-make (echo "exists") else (echo "not exists")

not working - shell always thinking that app is not exists (maybe because it not looking into PATH).
How to do this right and clean?

where checks, if the given file exists within the path (or on the current working folder %cd%) and gives either the full path(s) or an error message. Both you don't need - just the errorlevel:

where mingw32-make >nul 2>&1
if errorlevel 1 (echo "not exists") else (echo "exists")

or as a shortcut:

where /q mingw32-make && echo found || echo not found
