I did a test, but the make process complained "Cannot find source file
myobj.o". Which seems to be logical because the .o file needs to be
created first by ADD_CUSTOM_COMMAND.
What I have now is:
ADD_CUSTOM_COMMAND(TARGET mytest_gui PRE_LINK COMMAND ld -r -b binary -o
mytest_glade.o mytest.glade)
ADD_CUSTOM_COMMAND(TARGET mytest_gui PRE_LINK COMMAND objcopy
--rename-section .data=.rodata,alloc,load,readonly,data,contents
mytest_glade.o mytest_glade.o)
ADD_EXECUTABLE(mytest_gui main.cpp mytest_glade.o)
TARGET_LINK_LIBRARIES(mytest_gui ${GTKMM_LIBRARIES})
This obviously does not work because of a missing mytest_glade.o, but
how to circumvent that?
