- version.h is now static (should increase on new releases)
- if compiler flag is passed, will try to use version_auto.h (autogen)
(auto only on compiler flag to avoid include'ing a non-existant file)
- avoid clobbered version.h as may force recompiles
* Remove a couple TODO messages as they have already been done.
* Add check for parent directory to stop warning about there being no parent scope if building vgmstream directly.
* Remove the options for FDK-AAC and QAAC.
* Fix a few uses of CMAKE_CURRENT_SOURCE_DIR to use VGM_SOURCE_DIR (for consistency sake).
* Fix a few uses of CMAKE_BINARY_DIR to use VGM_BINARY_DIR.
* Add some conditionals for the install paths so they don't show if you aren't building something.
Makes plugins' STREAMFILEs not throw an error on non-existing .txtp
(normally written inside .m3u) treating it like a command/url-ish name.
This lets the TXTP parser to try to opening the virtual file with
commands, as 0-size TXTP with a formatted name is valid, like
"file.adx#l 1.0.txtp" ("play file.adx with 1 loop"), to allow quick
per-file config.
Also had to fix a few of the audacious files to get them to compile, mainly not using NULL in the input plugin constructor and casting the STREAMFILE functions (maybe some *nix compilers would've accepted those, but FreeBSD 12's Clang did not)
Needed to change how version.h was included to let it pick up the one from CMake's build location.
NOTE: Does not build with MinGW-w64 currently, does not have a way to build the audacious or XMPlay plugins.
