I don't think that is caused by the MAKEFLAGS removal I linked.
The code I linked does not run during 'cmake --build'. It only
runs while configuring a project to protect try_compile.
The problem is that make does not pass MAKEFLAGS when invoking a tool
it does not think is 'make'. For example:
-----------------------------------------------------------------------------
$ cat env.make
all:
@env make -f env.make other
other:
@echo MAKEFLAGS='$(MAKEFLAGS)'
$ make -j2 -f env.make other
MAKEFLAGS= -j --jobserver-fds=3,4
$ make -j2 -f env.make all
make[1]: warning: jobserver unavailable: using -j1. Add '+' to parent make
rule.
MAKEFLAGS=w
-----------------------------------------------------------------------------
You could try using "+env" as your COMMAND instead, though I wouldn't
consider this an officially supported approach.
