[Cmake] Building a common static lib from multiple directories...

[Andy Cedilnik]

Hi Jean,

What you can do is instead of using SUBDIRS, you include subdirectories:
PROJECT(Driver)

INCLUDE(${Driver_SOURCE_DIR}/drivers_1/CMakeLists.txt)
INCLUDE(${Driver_SOURCE_DIR}/drivers_2/CMakeLists.txt)
...

ADD_LIBRARY(drivers ${drivers_1_SRCS} ${drivers_2_SRCS} ...)

And all the CMakeLists.txt files would look like this:

SET(drivers_1_SRCS
    ${Driver_SOURCE_DIR}/drivers_1/toto.cpp
    ${Driver_SOURCE_DIR}/drivers_1/titi.cpp
    ...)

This will not create libdrivers_1.a and libdrivers_2.a, but you will
have the libdrivers.a. If you want those, you can always say:

INCLUDE(${Driver_SOURCE_DIR}/drivers_1/CMakeLists.txt)
INCLUDE(${Driver_SOURCE_DIR}/drivers_2/CMakeLists.txt)
...

ADD_LIBRARY(drivers_1 ${drivers_1_SRCS})
ADD_LIBRARY(drivers_2 ${drivers_2_SRCS})
ADD_LIBRARY(drivers ${drivers_1_SRCS} ${drivers_2_SRCS} ...)
