TDM-gcc is mingw-w64.
mingw-w64 is a mingw.
Mingws can be installed anywhere.
Mingws never register themselves in the system, unless a special
installer does it for them.
Autotools (primary buildsystem used with mingws) detects toolchain
presence by looking for compiler executable in current PATH.
If MSYS is used, MSYS is set up to add the toolchain's bin
subdirectory to PATH (user configures toolchain location in
/etc/fstab, and /etc/profile adds it to PATH when MSYS shell starts up)
If normal W32 shell is used, the it is advisable to create a W32 shell
script (.cmd or .bat) which would add toolchain's bin subdirectory to
PATH (and maybe set up other environment variables).
MSVC does have a shell script like that - it's called "Visual Studio
Command Prompt" in Start menu, and is actually a .cmd file by the name
"VC\vcvarsall.bat" in MSVS installation directory.

Please look for tools in PATH.

P.S. User can to add toolchain's bin subdir to system-level or
user-level PATH, but i would advise against it, since that makes it
difficult for user to have more than one toolchain active at once.
