Re: [CMake] Couple of library/link questions

Andreas Pakulat said the following on 3/20/2012 5:21 PM:

- The makefiles I'm basing this on build libevent_core.lib,
libevent_extras.lib and then libevent.lib which is basically the two
previous libraries merged.

I wanted to do:

ADD_LIBRARY(libevent_core ${CoreSrcFiles})
ADD_LIBRARY(libevent_extras ${ExtraSrcFiles})
ADD_LIBRARY(libevent)
TARGET_LINK_LIBRARIES(libevent libevent_core libevent_extras)

but this generates a warning/error,  listing the two libraries in

Whats the error? It should just work.
I mis-spoke; it gives a /warning/ for the ADD_LIBRARY(libevent) with no 
source files, warning that it is usually an error in the CMakeLists.txt 
file.

[CMake] Couple of library/link questions

2012-03-20 Thread Oliver Smith 
I'm trying to make a CMakeLists for libevent, and had a couple of 
questions that would make it a bit cleaner:


- Other than using a macro to do { add_executable(...) 
target_link_libraries(...) } is there a /clean/ way to make everything 
in a subdirectory automatically link a given library?


- The makefiles I'm basing this on build libevent_core.lib, 
libevent_extras.lib and then libevent.lib which is basically the two 
previous libraries merged.


I wanted to do:

ADD_LIBRARY(libevent_core ${CoreSrcFiles})
ADD_LIBRARY(libevent_extras ${ExtraSrcFiles})
ADD_LIBRARY(libevent)
TARGET_LINK_LIBRARIES(libevent libevent_core libevent_extras)

but this generates a warning/error,  listing the two libraries in 
add_library doesn't work either.


So for now I have

ADD_LIBRARY(libevent_core ${CoreSrcFiles})
ADD_LIBRARY(libevent_extras ${ExtraSrcFiles})
ADD_LIBRARY(libevent ${CoreSrcFiles} ${ExtraSrcFiles})

but that's clumsy :)

Hi Olivier,

Assuming you have not set the flag, BUILD_SHARED_LIBS [1] set to TRUE, I
will  consider you are building static libraries. If this last statement is
valid, it seems your approach is the right one.

I would also recommend you to read the following entry:
