`make docs` fails when (xe)latex is not installed. The output is pretty weird, looks like it's doing some `eval` tricks but something is blank:
/bin/sh: -output-directory=.: command not found
/home/tim/dev/rust/rust/mk/docs.mk:220: recipe for target 'doc/reference.pdf' failed
I have neither latex or xelatex installed. It seems like the following snippet is meant for me, but the logic is backwards:
ifeq ($(CFG_XELATEX),)
CFG_LATEX := $(CFG_XELATEX)
XELATEX = 1
else
$(info cfg: no xelatex found, disabling LaTeX docs)
NO_PDF_DOCS = 1
endif
I verified with:
$ make doc/reference.pdf CFG_XELATEX=/bin/foo
cfg: no xelatex found, disabling LaTeX docs
