[CMake] Get all required shared libs from a target

Hi Michael,
Thanks for your repsonse but I need the required DLLs to copy them in a post-build step. So I need the information which libaries are required for executing something. E.g., in your example
add_library(a ${A_SRCS})
add_library(b ${B_SRCS})
target_link_libraries(b a)
add_executable(c ${C_SRCS})
target_link_libraries(c b)
I`d like to have something like
GET_TARGET_PROPERTY(LIBS c IMPORTED_LINK_DEPENDENT_LIBRARIES) and then LIBS would contain "C:\project\a.dll;C:\project\b.dll". I also tried it with IMPORTED_LINK_DEPENDENT_LIBRARIES but that gives me an empty variable.
Hopefully, this made my problem clearer.
Michael

Hi
You don't need this (for the case you described). CMake remembers for
you:
add_library(a ${A_SRCS})
add_library(b ${B_SRCS})
target_link_libraries(b a)
add_executable(c ${C_SRCS})
target_link_libraries(c b)
As you see in the last line, c is mentioned to link against b. CMake,
however, remembers that b also links against a, and consequently also
adds a to the list of libraries to link against.
