CC/CXX/MinGW_HOME environment variables not set by setup/run script

[HumbleDeer]

It seems that the setup or "run me" script fails to set the environment variables CC, CXX and MINGW_HOME to their respective locations in the MinGW64 folder that MSYS creates during the initial setup.

This results in errors such as:

Where it cannot find the GCC binary, G++ binary or other MinGW locations.
In this particular example, they were referring to a location on my C drive, the default install location of MinGW.

pm3 ~/proxmark3$ set
[...]
CC=C:/MinGW/bin/gcc.exe
CXX=C:/MinGW/bin/g++.exe
MINGW_HOME=C:/MinGW/
[...]

This would've worked if MinGW was installed there. Mine wasn't, which revealed this problem.

The solution would be to use the same relative paths or variable based paths as the makefile script does, where it assigns these variables relative to the ProxSpace "home" (msys folder)

In my case, this was done by setting them from the terminal:

export CC=/mingw64/bin/gcc.exe
export CXX=/mingw64/bin/g++.exe
export MINGW_HOME=/mingw64/

Although these are clearly absolute paths meant to be used in the environment set up by MSYS.
