Migrate to CMake

[atirut-w]

This should help keep build scripts clean and easy to maintain while also preventing spontaneous combustion of the build scripts. WIP.

Tools:

• Tests
• appmake
• copt
• sccz80
• ticks
• ucpp
• z80asm
• z80nm
• zcc
• zobjcopy
• zpragma
• zsdc
• zx0
• zx7

Issues:

• copt: can't open patterns file
• cannot open peep rule file¹
• Consider migrating libsrc in a separate PR²
• zcc: syntax error when compiling the test file from the installation tutorial. May be related to z80asm

Footnotes

1. I have absolutely no idea where this one is coming from. ↩

2. The current Makefile script for libsrc is a huge chonk. I haven't even made sense of most of the steps it does yet. ↩

The current Makefile script for libsrc is a huge chonk. I haven't even made sense of most of the steps it does yet.

It's tracking a huge number of dependencies and generating 65k object files and the best part of 350 libraries. Don't go there.

cannot open peep rule file

I think that's sdcc.

Installing libsrc fixed it for me, but thanks 👍.

Ah yeah, the rules for sdcc are located in $ZCCCFG/../../libsrc/_DEVELOPMENT

The essential parts are done now, I think. It builds and can compile the example C source file. Not sure where the remaining utils come in, but all that's left would be polishing up the build scripts and implementing tests.
