In a move to avoid convenience libraries, I have tried to store a list of
files into a variable ("utils_SRCS"), and reuse this var in each target that
would normally link to the convenience lib (potentially compiling these
source files multiple times, but that is not the issue here).
[snip file list]
---src/CMakeLists.txt---------
ADD_SUBDIRECTORY( utils )
ADD_SUBDIRECTORY( mylib )
---src/utils/CMakeLists.txt---------
SET(utils_SRCS a.cpp b.cpp)
---src/mylib/CMakeLists.txt---------
ADD_LIBRARY(mylib l1.cpp l2.cpp main.cpp ${utils_SRCS} )
But now, in src/mylib/CMakeLists.txt, the ${utils_SRCS} is always empty,
resulting in missing symbols when linking. I have tried to print some STATUS
messages, and the control flow between the cmake scripts is what I expect,
but the variable is defined only in the src/utils/CMakeLists.txt, after that,
it's gone. What is the logic behind this ?
WAG: variables only propogate to children, not siblings (i.e. 'not to
later CMakeLists.txt's that are not children)? IOW, try moving your
SET() up to a common parent.
(hmm, an appropriate .sig...)
