This establishes (near) parity of source code file lists
between the Makefile and CMakeLists.txt
To make that change I messed around CMakeLists.txt a bit.
It now uses target_sources and target_compile_definitions.
I also removed some MSVC stuff since we don't actually
care about MSVC--it made things easier.
CMake minimum version 3.0 -> 3.13 for target_sources.
Some key points for programmers:
- Source code files are mostly listed in a 'Sourcefile'.
So you no longer directly edit the object list. There
can be multiple Sourcefiles and they can even live in
subdirectories--the directory name will be prepended to
every filename in the list. Of course, the Makefile
still needs to be edited to read from each Sourcefile.
- Different rules are no longer required for source code
files that live in subdirectories (such as sdl/ or
hardware/). Subdirectories Just Work so go ham!
In addition to those points, another important change is
that the bin directory is no longer divided into platform
subdirectories (Linux64, Mingw, etc). Executables now go
directly into bin. If you use DEBUGMODE or target 64-bit,
then subdirectories for 'debug' and '64' will be made
though.
Oh by the way, I don't think make clean actually removed
files before on Windows. It should now. I also fixed as
many little inconsistencies like that as I noticed.
And now just an overview of the technical aspects that
shouldn't affect anyone who doesn't REALLY care about the
Makefile...
objs and dep directories have been moved to a make
directory. Makefile.cfg and its variants have been moved
out of their various subdirectories to src/Makefile.d
make distclean removes the bin and make directories
entirely, but make clean and cleandep still only affect
the current build target.
When I say automation, I mean that a lot of copy pasting
in the Makefile has been reduced.
See 7df6a309 and 83a87042. I didn't realize that light
userdata's metatable is shared--like numbers or strings.
So it cannot be paired with a metatable.
I also made a few minor tweaks to Lua cvars, other than
accounting for the double pointer in the userdata.
- If a level is in-between two with the same header, it would previously create two headers with the same name. Now it groups all levels with the same header together.
- Previously, a header would only be visible if its first map was visible. Now it will show the header if you've visited any level under the header.
For SUGOI.
