Hello,
I build a project which consists of several "modules" with various mutual
dependencies. Each module defines its OBJECT target as:
# Module 1:
add_library(Module1 OBJECT ....)
target_include_directories(Module1 PRIVATE ${CMAKE_CURRENT_SOURCE_DIR})
add_library(Module1_LIBRARIES INTERFACE)
target_link_libraries(Module1_LIBRARIES INTERFACE $<BUILD_INTERFACE:....>)
# Module 2:
add_library(Module2 OBJECT ....)
target_include_directories(Module2 PUBLIC
$<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}>)
add_library(Module2_LIBRARIES INTERFACE)
target_link_libraries(Module2_LIBRARIES INTERFACE $<BUILD_INTERFACE:....>
$<BUILD_INTERFACE:Module1_LIBRARIES>)
add_library(Module2_INCLUDES INTERFACE)
target_include_directories(Module2_INCLUDES INTERFACE
$<TARGET_PROPERTY:Module2,INCLUDE_DIRECTORIES>)
target_sources(Module2_INCLUDES INTERFACE ....)
add_library(Module_CONFFILE INTERFACE)
target_sources(Module2_CONFFILE INTERFACE Module.config)
And when building a final product (or one of the final products), I use the
individual targets:
add_library(Product1 STATIC $<TARGET_OBJECTS:Module1>
$<TARGET_OBJECTS:Module2> ...)
target_link_libraries(Product1 LINK_INTERFACE_LIBRARIES
$<BUILD_INTERFACE:Module1_LIBRARIES> $<BUILD_INTERFACE:Module2_LIBRARIES> ...)
It works perfectly, the library is built using all the sources. Even when
defining INSTALL, all the properties of the targets (include files, config
files, etc.) can be accessed and are installed correctly
install(TARGETS Product1 DESTINATION "./" EXPORT "libProduct1")
install(FILES $<TARGET_PROPERTY:Module2_CONFFILE,INTERFACE_SOURCES>
DESTINATION "./config")
install(FILES $<TARGET_PROPERTY:Module2_INCLUDES,INTERFACE_SOURCES>
DESTINATION "./include")
The problem starts when I want to export a CMake file listing all the libraries
which were defined by the individual modules (and are accessed by
$<BUILD_INTERFACE:Module2_LIBRARIES>) since they know what they need (how they
were configured).
When building a static library (which is shown here), I need to export a list
of additional libraries necessary to link the Product1 correctly. But using
$<BUILD_INTERFACE:Module[]_LIBRARIES> in the INSTALL() command does not work,
neither works something like:
install(EXPORT "llibProduct1" DESTINATION "."
EXPORT_LINK_INTERFACE_LIBRARIES)
So the question is: how to export the libraries defined by the individual
modules to an CMake file which would be installed together with the Product1
library and header files?
Thank you very much,
Dan
P.S. I use CMake 3.6.2.
