Handle different build systems #11
Description
Right now it just runs make (not even make install!) a possible future version of RGBDS may change this.
Ideas floated about in the chat include:
- Detect Cargo.toml or Makefile, and run build commands accordingly. If Cargo build command is hardcoded into rgbenv, it may introduce incompatibilities.
- Always use Make. Some amount of anachronism is to be felt when having a Makefile that runs Cargo... but I think could work.
- Detect Makefile, and if not present try running build.sh. Gets rid of hard dependency on Make.
