CMAKE- Object library target may not link to anything
I am getting an error with the cMakeLists.txt file below. The error is
Object library target "cm" may not link to anything.
The issue is with line target_link_libraries(cm corebase)
This builds OK on linux but I this error is occurring on windows.
I'd appreciate any ideas?
file(GLOB base
"*.cpp"
)
file (GLOB model
"*.cpp"
)
file(GLOB logger

file(GLOB pass

The error message is correct: OBJECT libraries shouldn't link to anything. Instead, one need to use object files, corresponded to the library, as source files for executable/other library:
# Create an OBJECT library
add_library(corebase OBJECT ${base} ${logger})
# And use its objects for other library.
add_library(cm OBJECT ${compiler} ${pass} $<TARGET_OBJECTS:corebase>)
