REM Configure (if needed) and build the project, preferably with Ninja.

REM
|
|
REM Usage (from the project root):
|
|
REM scripts\build.bat [BUILD_TYPE] [extra cmake -D args...]
|
|
REM
|
|
REM BUILD_TYPE Debug^|Release^|RelWithDebInfo^|MinSizeRel (default: Release)
|
|
REM
|
|
REM Anything after BUILD_TYPE is passed straight through to cmake's
|
|
REM configure step, e.g.:
|
|
REM scripts\build.bat Debug -DBUILD_EXAMPLES=ON -DBUILD_TESTS=ON
|
|
REM CMake caches -D options across reconfigures, so passing them once and
|
|
REM then calling scripts\build.bat plain afterward for incremental builds
|
|
REM keeps them set -- no need to repeat them on every call.
|
|
REM
|
|
REM Set BUILD_DIR to build somewhere other than out\build (see Configuration.cmake).

REM Deliberately NOT %1/%2/... for this: cmd.exe's own parameter
|
|
REM parser treats = (along with , and ;) as an argument separator, so
|
|
REM "-DBUILD_EXAMPLES=ON" typed as one argument arrives as %2=
|
|
REM "-DBUILD_EXAMPLES" and %3="ON" -- two arguments, with the = gone --
|
|
REM before this script ever sees it, corrupting any -D value passed
|
|
REM this way and silently breaking the configure step below. %* does
|
|
REM not go through that same parser and reflects the command line
|
|
REM as typed, and FOR /F's own tokenizer only splits on space/tab, so
|
|
REM routing %* through "tokens=1,*" correctly separates just the
|
|
REM first word from everything after it, = signs and all -- verified
|

REM directly (via Wine's cmd.exe) against exactly the failure the
|
|
REM old %2 %3 %4... version had, not just reasoned through.

REM Prefer a pinned ninja (fetched by scripts\setup.bat -- see
|
|
REM cmake\FetchNinja.cmake) over a system one, same "always the pinned
|
|
REM copy" preference as Doxygen. Deliberately goto-based, and deliberately
|
|
REM `pushd` + a bare wildcard rather than `for /d %%D in ("path\*")` --
|
|
REM both tested directly; a path-prefixed wildcard didn't match here,
|
|
REM this form does, and it also sidesteps nesting a FOR loop inside an
|
|
REM if/else block, which separately corrupts cmd.exe's paren-matching for
|
|
REM the enclosing block (see scripts\refactor.bat for that one).
