Hi,
I am trying to dynamically assemble a list of generator expressions and use
them in add_executable. The background is that I have some macros to add
targets, e.g.
add_my_library(TARGET liba SOURCES ...) # this class add_library(liba OBJECT
...) internally
add_my_executable(TARGET a DEPENDS liba libb SOURCES ...)
In add_my_executable, I create a list of $<TARGET_OBEJCTS:${d}> strings for all
d {liba, libb}. However, cmake complains that it cannot find the source file
$<TARGET_OBJECTS:liba>.
A simplified example of what I want to do is this:
add_library(A OBJECT a.cpp)
set(alib $<TARGET_OBJECTS:A)
add_executable(a.exe ${alib})
add_executable(b.exe $<TARGET_OBJECTS:A> )
With cmake 3.2.2, the first add_executable fails, the second one works. Is
there another way to do this?
Best wishes,
Jens
