I have an executable depends on some nonexisting files.I use
ADD_CUSTOM_COMMAND to produce these files. However, make reports "no
rule" errors even rules are there. Type "make envC.cpp" directly works
instead.
The rule in the Makefile:
envC.cpp: /home/ship2rr/hdrsfaults.h
@echo "Building Custom command envC.cpp..."
/usr/bin/soapcpp2 -x -w -L -n -penv /home/ship2rr/hdrsfaults.h
scheduler: $(scheduler_SRC_OBJS) $(scheduler_EXTERNAL_OBJS)
$(scheduler_DEPEND_LIBS)
@echo "Building executable /home/ship2rr/test/scheduler..."
c++ -fPIC $(scheduler_SRC_OBJS) $(scheduler_EXTERNAL_OBJS) -o
/home/ship2rr/test/scheduler ...
Here is output from make:

My questions are:
A) Is this a bug of cmake or how can I correct it to make it work?
B) If I use ADD_CUSTOM_TARGET and ADD_DEPENDENCIES as showed between
question marks, it will not work. It still compiles encV.cpp first
instead of producing custom-defined targets. However, if I manually move
$(scheduler_DEPEND_LIBS) before $(scheduler_SRC_OBJS) in the above
second rule,
it works. How can I make sure my custome-defined targets be built first
or is there a method to specify the order of dependencies?
Thank,
Tao
